If I could keep only one top in a client's wardrobe, it would probably be a good button-up. It tucks into trousers, layers under knits, opens over a tank, and you can knot the hem when you want it shorter. What changes the mood is mostly fabric: crisp poplin looks sharp, linen and chambray look relaxed, satin goes out at night. Below are 50 ways to wear one, from straight jeans to pencil skirts, plus the fit checks and tucking methods I use every time I style a shirt.

Fitting a Shirt From the Shoulder Down
Most shirts that look wrong are the wrong size in one place, not everywhere. When I fit a button-up, I check it in this order, because the first two are the hardest to alter.
- Shoulders. On a fitted shirt the shoulder seam should sit at the edge of your shoulder bone. On an oversized shirt it's meant to drop, but it shouldn't hang halfway to the elbow unless that's clearly the design.
- Bust. Button it up and stand side-on to a mirror. If the placket pulls into small gaps between buttons, size up. A tailor can take in a waist easily; adding room across the bust is close to impossible.
- Sleeves. With your arms relaxed, the cuff should land at the wrist bone. Too long is fine if you roll; too short looks like you've outgrown it.
- Length. A curved shirttail hem is cut to be tucked. A straight hem is meant to be worn out. Check which one you have before choosing how to wear it.
If the bust gapes only slightly, a small hidden snap or a piece of double-sided fashion tape between the buttons solves it without buying a new shirt.
1. White Button Up Top With Straight Leg Jeans

White shirt, straight-leg jeans: the outfit I build every capsule wardrobe around. Medium wash keeps it relaxed, dark wash makes it office-ready. A full tuck with a slim leather belt shows the waist. If it feels too stiff, open the second button and roll the sleeves to just below the elbow. Petite frames suit ankle-length jeans; taller ones can let a full-length hem break gently over the shoe.
2. Oversized Button Up Top With Black Leggings

An oversized shirt over black leggings is my fix for days that need comfort and still have to look put together. The shirt should cover the seat, nothing more, or it starts swallowing you. Wear a fitted tank underneath and leave the lower buttons open so you can walk freely. Pushing the sleeves to the elbow shows your wrists, which makes the whole shape look less boxy.
3. Blue Button Up Top With White Jeans

Pale blue cotton with white jeans looks fresh in spring and summer. A front tuck shows the waist while the back falls loose over the seat. White denim needs to be thick enough not to show pockets and seams through, so I always check in daylight and wear skin-tone underwear. Tan sandals and gold jewelry warm the cool palette.
4. Striped Button Up Top With Wide Leg Trousers

Stripes add structure to wide-leg trousers without making things formal. A blue-and-white stripe with navy, camel, gray or cream high-waisted trousers is the classic version. Vertical stripes also lengthen the torso, which helps balance a wide leg. Tuck smoothly, and wear pointed flats or low heels if the trousers nearly skim the floor.
5. Linen Button Up Top With Tailored Shorts

In real heat, a linen shirt with tailored shorts covers your shoulders without trapping warmth. White, sand, light blue or sage all look calm. Linen wrinkles within minutes of sitting down; I treat that as part of its charm rather than fighting it. Tuck the front or knot the hem loosely, and choose longer shorts with a relaxed opening if you want more coverage.
6. Black Button Up Top With Beige Trousers

Black shirt, beige trousers: a neutral contrast you can repeat all week. A fluid shirt looks softer, crisp poplin sharper. Leave it untucked only if it ends near the hip; longer shirts need a full or partial tuck, or the legs look short. Black loafers and a black bag tie the top and feet together.
7. White Button Up Top With Satin Midi Skirt

Crisp cotton against fluid satin is one of my favorite texture contrasts. Tuck a white shirt into a bias-cut midi in black, champagne, olive or chocolate. Satin clings at the waist and shows every fold of shirting underneath, so I tuck carefully and smooth the fabric flat, or use a bodysuit-style shirt with no loose tails. Pointed flats for day, heeled sandals for evening.
8. Chambray Button Up Top With White Pants

Chambray looks like denim but is lighter and softer, so it tucks far more easily. Pair a chambray button-up top with white straight or wide-leg pants. Cognac loafers and a brown belt pull the palette together. If the shirt is oversized, wear it open over a white tank; the long open edges create vertical lines that lengthen the body.
9. Satin Button Up Top With Dark Wash Jeans

A satin shirt turns dark jeans into an evening outfit. Choose a jewel tone, soft neutral or black with a fluid drape, and tuck into high-rise straight jeans. Satin shows sweat and water marks, and a lace bra shows through it as texture, so I wear a smooth camisole or seam-free bra underneath. Keep jewelry minimal; the sheen already does the work.
10. Cropped Button Up Top With High Waisted Jeans

A cropped shirt works best when the hem meets or nearly meets the jeans' waistband. Boxy white, striped or pastel shirts with relaxed straight denim look current. Very loose crops need a cleaner waistband below so the outfit doesn't look like two big shapes. Layer a thin tank underneath if you want zero skin.
11. Button Up Top With Denim Maxi Skirt

A shirt gives a long denim skirt some shape. With a wide skirt, choose a fitted shirt; with a narrow skirt, a roomier one. A front slit makes walking and stairs possible. Tuck in and add a medium-width belt. White, striped and light blue shirts look crisp against dark denim.
12. Plaid Button Up Top With Black Jeans

Plaid with black jeans is a cool-weather staple. I pick a plaid that already contains black, gray, cream, green or burgundy so it links to the denim. Wear it buttoned and front-tucked, or open over a fitted tee. With flannel, keep the underlayer thin; thick flannel over a bulky tee adds heft quickly. A black leather jacket finishes it.
13. Pink Button Up Top With Gray Trousers

Pink brings warmth to gray trousers. Blush is subtle; a brighter pink gives more color. Thin pink cotton often shows a white bra clearly, so I use a camisole close to your skin tone instead. Gray loafers keep it neutral; nude pumps make it more formal. A charcoal blazer ties it together for work.
14. Green Button Up Top With Cream Pants

Green shirts look fresh with cream pants. Olive and forest suit autumn, sage and emerald suit spring. Tailored cream trousers for work, relaxed linen pants for weekends. Brown loafers or tan sandals and a cognac bag keep the palette earthy. A full tuck defines the waist; a half tuck softens it.
15. Button Up Top With Pleated Midi Skirt

A pleated midi moves, and a structured shirt anchors it. Tuck firmly so the shirt doesn't pull loose as you walk. Tonal cream-on-beige looks elegant; a white shirt with a colored skirt feels playful. Keep the shirt smooth, because excess fabric bunched at the waist pushes pleats outward and widens the hips.
16. Short Sleeve Button Up Top With Linen Pants

Short sleeves and linen pants are my answer to humid days. Look for a relaxed collar and enough room in the sleeves to move. High-rise wide-leg linen pants in white, oatmeal, khaki or black work. A front tuck stops the outfit looking shapeless. A tonal palette, like oatmeal on oatmeal, looks surprisingly refined.
17. Oversized Button Up Top With Bike Shorts

An oversized shirt over bike shorts and a tank is the off-duty version. White, pale blue and stripes work with black shorts. Fasten a couple of center buttons or leave it open. The shirt should reach below the widest part of the hips if you want coverage. Check the shorts are thick enough to stay opaque when you bend.
18. Button Up Top With Leather Pants

A shirt softens leather pants. Crisp white gives strong contrast; tonal black looks sleek. Straight-leg leather is easier to wear than skin-tight. If the pants are glossy, I choose a matte cotton shirt, because two shiny surfaces cancel each other out. Pointed boots or loafers finish it.
19. Button Up Top With Cargo Pants

Cargo pants look sharper with a clean shirt. A fitted white shirt with olive, tan or black cargos, or a softly oversized stripe with relaxed ones. A neat front tuck stops the pockets from piling up with shirt fabric. Pointed flats are an unexpected, smart touch. If the pants are very loose, a shorter shirt keeps things in proportion.
20. Denim Button Up Top With Black Trousers

A denim shirt adds friendly texture to black trousers. Choose lightweight denim or chambray, since heavy denim tucks into trousers with obvious bulk. Straight or wide trousers with a clean waistband work best. Roll the cuffs once or twice. Silver jewelry suits the cool blue.
21. Button Up Top With A-Line Mini Skirt

A shirt with an A-line mini is balanced because both pieces have structure. Tuck into a high-waisted skirt in denim, corduroy or wool. Loafers with ankle socks look classic; knee boots add coverage in cold weather. With a short skirt, I keep the neckline a little more buttoned up. A jacket that ends at the waistband keeps the skirt shape visible.
22. Button Up Top With Flared Jeans

Flared jeans and a tucked shirt create a gentle retro shape. Choose high-rise denim so the waist shows before the flare. Crisp white is classic; patterned or satin adds personality. Platforms or heeled boots let the flare fall properly. Petite frames do better with a smaller flare and similar colors top and bottom.
23. Button Up Top With Sweater Vest And Jeans

A sweater vest over a shirt is a smart layer for in-between weather. Start with a white or striped shirt and add a crew or V-neck vest in cream, camel, gray or navy. Let the collar and cuffs show. On a fuller bust, a V-neck vest in a flexible knit breaks up the chest area and avoids a boxy look.
24. Button Up Top Under A Blazer With Jeans

Shirt, blazer and jeans form the smart-casual uniform. A crisp white, blue or striped shirt under a relaxed blazer with dark jeans works almost everywhere. Push the blazer sleeves up slightly so the shirt cuffs show. I check the jacket has room across the shoulders and bust over the shirt; a blazer that pulls when buttoned over shirting is a size too small for layering.
25. Button Up Top With Paperbag Waist Pants

Paperbag pants put the focus on the waist, so the shirt needs to tuck neatly. A fitted, cropped or lightweight shirt avoids extra fabric under the gathers. Neutral camel, navy, olive or black pants suit white and colored shirts. Tie the belt in a compact knot and keep the bag plain.
26. White Button Up Top With Black Midi Skirt

A white shirt and black midi is a contrast you can't get wrong. Tuck into a straight, pleated or softly flared skirt. Black loafers by day, slingbacks for something more formal. Rolling the sleeves stops the outfit feeling too corporate. In winter, add sheer tights and a long coat.
27. Printed Button Up Top With Neutral Trousers

A printed shirt becomes the focus when everything else stays quiet. Geometric, abstract, floral or small motifs all work with black, cream, navy or camel trousers. I pull one neutral from the print and repeat it in the pants, shoes and bag. On a fuller figure, an evenly spaced print in a fluid fabric that skims rather than clings is easiest.
28. Button Up Top With Bermuda Shorts

Bermuda shorts give coverage with a summer feel. Tailored black, navy, beige or white shorts with crisp cotton or linen work. Tuck the shirt in to balance the longer short. With a wide leg opening, keep the shirt fitted through the shoulders. A matching belt sharpens it.
29. Button Up Top With Slip Dress

An open shirt over a slip dress makes it a daytime outfit. Choose an oversized cotton, linen or chambray shirt and wear it like a light jacket, or knot it at the waist. Related tones look calm; white over a bright dress gives contrast. It also covers your arms for air-conditioning and sun.
30. Button Up Top With Knit Maxi Dress

A roomy open shirt adds structure to a clingy knit maxi dress. White, chambray and stripes go with most solid dresses. Knot it loosely at the front for waist definition, or choose a cropped shirt to avoid fabric around the hips. Easy for travel days and changing temperatures.
31. Button Up Top With Joggers

A shirt makes joggers look like real clothes. Tapered black, navy, gray or olive joggers with a white or blue oversized shirt worn open over a tank work. Loafers instead of sneakers give a nice high-low contrast. Don't pair very loose joggers with a very long shirt; keep one of them streamlined.
32. Button Up Top With Relaxed Suit

A relaxed suit becomes more versatile with a shirt underneath. A white fitted shirt gives crisp contrast; a tonal one creates a long, unbroken line. Tuck it in and leave the collar slightly open. If the suit is oversized, the shirt must fit cleanly through the shoulders, otherwise you're wearing three loose layers.
33. Button Up Top With Corduroy Pants

Corduroy and a shirt suit autumn. Rust, olive, camel or chocolate cords with a white, cream, chambray or plaid shirt look good. Corduroy is already textured, so I keep the shirt smooth. A light shirt also brightens the deeper seasonal colors. Ankle boots or loafers should stay visible below straight legs.
34. Button Up Top With Khaki Pants

Shirt and khakis can look casual, preppy or professional. A full tuck and leather belt is traditional; rolled sleeves and a front tuck are relaxed. To avoid looking like a uniform, I change one proportion: wide-leg khakis, an oversized shirt or a cropped jacket. A brown bag connects to the khaki.
35. Button Up Top With Pull-On Wide Leg Pants

Pull-on wide-leg pants are comfortable, and a shirt gives them structure. A front tuck shows the waist without drawing attention to the elastic. Choose a tonal palette for one long line. With patterned pants, a solid shirt in one of the quieter colors keeps it calm.
36. Button Up Top With Pencil Skirt

A shirt and pencil skirt is the classic office pairing. The fit across the bust matters most: if the placket gapes between buttons, the shirt is too small there, and I'd size up and tailor the waist rather than squeeze. Tuck into a knee-length or midi pencil skirt with a back slit. Avoid bulky belt buckles under a jacket.
37. Button Up Top With Tiered Maxi Skirt

A tiered maxi has lots of movement, so a tucked shirt gives it structure. A solid white or chambray shirt suits a printed skirt; a colorful shirt suits a plain one. If a full tuck feels bulky under the gathered waist, knot the shirt instead. Petite frames suit smaller tiers and a higher waist.
38. Button Up Top With Overalls

A shirt under overalls is more polished than a tee. Choose fitted or lightly relaxed shirting so it sits flat under the bib. Denim overalls suit white, striped or pastel shirts; black overalls take brighter colors and prints. Roll the overall hems if they're loose. Leaving the top shirt button open softens the neckline.
39. Button Up Top With Knit Cardigan And Jeans

A cardigan over a shirt is cozy but still structured. Let the collar and cuffs show. With a cropped cardigan, tuck the shirt or let only a narrow strip of hem peek out. With a long cardigan, choose a slim shirt to avoid fabric piling at the hips. Straight jeans keep it classic.
40. Button Up Top With Trench Coat And Jeans

A trench over a shirt and jeans is a practical transitional outfit. Tuck in a crisp white or blue shirt and add a belt. Leave the trench open or tie the belt loosely behind. I check the coat hem against the jean length; a coat ending exactly where the jeans crop looks choppy. Loafers or ankle boots finish it.
41. Button Up Top With Puffer Vest And Leggings

For cool, casual days, wear a long button-up top with opaque black leggings and a lightweight puffer vest. The shirt should extend below the vest and cover the hips. Keep the vest slightly fitted to avoid bulk. A striped or chambray shirt adds interest under a solid vest.
42. Button Up Top With Cropped Trousers

Cropped trousers show the ankle and keep the outfit clean. Choose straight or tapered pants ending just above the ankle bone, with a tucked shirt. Matching the shoe to the trousers keeps the leg long. Shorter legs look better without heavy ankle straps, which cut the line.
43. Button Up Top With White Shorts

A colorful or striped shirt stands out against white shorts. Tailored, denim or linen shorts all work; tuck the shirt or knot the shirt at the waist. Check white shorts in daylight for show-through, especially pocket linings. If the shirt is oversized, wear it open over a fitted tank.
44. Button Up Top With Utility Skirt

A utility skirt adds practical details to a classic shirt. A midi or knee-length skirt in khaki, olive, navy or black with flat patch pockets works. Tuck in a fitted white or striped shirt. Utility skirts can look heavy, so I keep the top light-colored and the ankles visible.
45. Button Up Top With Matching Shorts Set

A matching shirt and shorts set needs almost no thought. Linen, cotton or a light textured fabric in a neutral, pastel or stripe work. Tuck one side of the shirt into the shorts or wear it open over a tank. Buy a set whose shirt also works with jeans; you'll get twice the wear.
46. Button Up Top With Knee High Boots And Skirt

A shirt, midi skirt and knee boots work well in cold weather. The skirt hem should overlap the boot shaft or leave only a narrow gap. Tuck in a fitted shirt; with an oversized one, do a full tuck and blouse the fabric slightly above the waistband. A wool coat completes it.
47. Button Up Top With Mom Jeans And Loafers

Mom jeans and loafers give a shirt a relaxed classic finish. Tuck a white, chambray or striped shirt into high-rise jeans and add a belt that matches the loafers. Only cuff the jeans if they bunch over the shoes. Show crew socks in winter, liners in summer.
48. Button Up Top With Monochrome Trousers

A monochrome shirt-and-trouser outfit looks polished with very little effort. Ivory with cream, navy with dark blue, chocolate with camel: shades don't need to match exactly. Tuck into high-waisted trousers and match the shoes. If pale colors feel hard to wear, start with navy, gray or brown.
49. Button Up Top With Graphic Tee And Jeans

An open shirt over a graphic tee and jeans is an easy layer. Choose a solid, stripe, plaid or denim shirt that picks up a color from the graphic. Keep the graphic simple if the shirt is patterned. Roll the sleeves, tie it around your waist when it warms up, or fasten a few lower buttons.
50. Button Up Top With Sequin Midi Skirt

A shirt makes a sequin midi feel refined. A crisp white, black or tonal satin shirt tucked in, with the neckline open and sleeves slightly rolled, contrasts nicely with the shine. Plain pointed flats or pumps work better than decorated shoes. Matte sequins in black, silver or champagne are the subtler choice.
Four Tucks and When I Use Each
- Full tuck: the whole hem goes in. Best with tailored trousers, pencil skirts and anything with a defined waistband. Raise your arms once afterward to loosen the fabric slightly so it doesn't look pulled tight.
- Front tuck: only the front few inches go in, the back hangs loose. This is my default with jeans; it shows the waist and hides the seat.
- Side tuck: one side tucked, the other out. It adds a diagonal line and works with relaxed shirts and high-rise denim.
- Knot: tie the two front tails at the waist. Best with thin cotton and linen shirts over skirts or wide pants, where a tuck would add bulk.
For sleeves, I use what's often called a master roll: fold the cuff up to just below the elbow, then fold the bottom of that up again so the cuff is trapped inside, leaving just its edge showing. It stays put far better than repeated small rolls.
Collars and Cuffs That Stay Crisp
Collars and cuffs are where a shirt starts to look tired first. Skin oils leave a grey ring inside the collar, so I rub a little liquid detergent or dish soap into it before every wash rather than waiting until it's visible. Wash shirts buttoned up, so the fabric doesn't twist out of shape.
When ironing, do the collar first, working from the points inward so creases don't form at the tips, then the cuffs, then the sleeves, then the body. Hang shirts on shaped hangers with the top button done up, which keeps the collar standing properly. Linen and cotton can go on a hanger slightly damp, where most of the creases will fall out on their own.
Get the Fit Right and the Shirt Does the Rest
One familiar shirt can handle casual, work, sporty and dressy outfits. Start with pieces you already own, like jeans, black trousers, leggings or a midi skirt, then play with fabric, color, layers and tucks. Balance oversized shirts with slim bottoms and tuck fitted ones into wider shapes. Above all, buy a shirt that fits your shoulders and bust properly; once that's right, every outfit here gets easier.
