Girls' activewear has quietly become the school uniform for a lot of families, and for good reason: it moves, it washes, and kids actually agree to wear it. The trick is making it look like an outfit rather than gym kit pulled on in a hurry. Below are twenty combinations built around Athleta Girl tees, tanks, polos, sweatshirts and hoodies, paired with everything from bike shorts and tennis skorts to joggers and denim. The rule I lean on most is simple: shorter, sport-length tops need a high-rise bottom, and roomy sweatshirts need something fitted underneath. Get that balance right and almost any color combination works, so let your daughter pick the shades and adjust coverage to her school's dress code.
Buying Room to Grow Without a Sloppy Fit
Every parent wants kids' clothes to last more than one season, but sizing up across the board is where activewear goes wrong. Leggings and bike shorts that are too big sag at the seat and slide down during running, and an oversized tank gapes at the armholes. I size by job instead.
- Bottoms: buy true to size. A waistband needs grip to stay up during play, and that's the part that fails first when it's too loose.
- Sweatshirts and hoodies: going one size up is fine here. A relaxed fit is the intended look, and pushed-up sleeves hide the extra length.
- Fitted tees and tanks: stay true to size, or the hem sits too long and bunches under jackets and skort waistbands.
- Polos: check the shoulder seam. It should sit on the shoulder bone, not halfway down the arm.
Then do the arm-raise test. Ask her to reach both hands overhead. If the tee lifts well above the waistband, that pairing needs a higher rise, not a longer top. Most performance knits have some stretch, so a snug fit today will usually still work after a growth spurt in height, even when the length starts to run short.
1. Athleta Girl Power Up Tee With Bike Shorts
Bike shorts are the easiest place to start because the high waistband does the coverage work for you. I pair a sport-length Power Up tee with black, navy or charcoal shorts so a bright top stays the focus. The tee's hem should land on or just over the waistband when she raises her arms; if skin shows every time she reaches, size the shorts up in rise, not the tee in length. Cushioned white sneakers and ankle socks suit outdoor games, and a zip jacket tied at the waist handles a warm afternoon. A small backpack and a headband finish it.
2. Athleta Girl Right Moves Tee With Leggings
This is the outfit I'd lay out the night before a rushed school morning. A Right Moves core tee over full-length black leggings handles class, recess and after-school clubs, and a relaxed denim jacket on top is what stops it reading as pure gym wear. Check the tee under the jacket in the mirror: a too-long tee bunches at the back of the jacket hem and looks sloppy. Lavender, blue or green tees all sit well against black. Low-top sneakers and a scrunchie are enough, and in colder months I swap the denim for a fleece-lined zip hoodie.
3. Athleta Girl Rib Scoop Tank With Tennis Skort
Skorts only work for active kids if the built-in shorts are real shorts, with a snug leg that doesn't ride up. Pair a ribbed scoop tank and tennis skort for hot days, keeping the top pale or softly striped against a navy or black bottom. Ribbed knits cling slightly, which is why a fitted tank sits neatly at the skort waistband instead of flapping. Crew socks and clean court sneakers suit lessons and camp. If the cropped tank feels too short for her, a longer scoop shape or a fitted tee underneath fixes it, and an open button-front shirt covers shoulders between activities.
4. Athleta Girl Rib Scoop Tee With Wide Leg Pants
Wide-leg pants on kids can swamp them unless the top is close-fitting, so a rib scoop tee is the right partner here. I go high-rise in black, gray or navy and let the tee bring the color. If the tee ends at the waistband, leave it out; a longer one gets a small front tuck so the leg line starts at the waist. Performance fabric matters more on wide legs than slim ones, since heavier cotton creases behind the knees after a morning at a desk. Retro sneakers, a canvas tote and a cropped zip jacket finish it for school or travel days.
5. Athleta Girl All Day Sweatshirt With Joggers
Matching is optional with a crewneck sweatshirt and matching joggers; tone-on-tone actually looks more grown-up. Light gray with charcoal, or pale blue with navy, reads as planned without the pajama effect of an exact set. I always put a fitted white tee underneath because classrooms swing between drafty and overheated. Pushing the sleeves up slightly keeps the All Day sweatshirt from looking two sizes too big. Running sneakers, ribbed socks and a roomy backpack suit cool school days and long car rides, with a belt bag for travel.
6. Athleta Girl School Day Polo With Pleated Skort
A polo is the piece that makes activewear acceptable at schools with stricter dress codes. Combine a School Day polo in white, light blue or navy with a solid pleated skort in a color the school allows. A half tuck at the front defines the waist but still leaves room to run, and the built-in shorts under the pleats mean she can sit on the floor without fuss. On chilly mornings I'd add a thin crewneck sweater with the collar pulled out. Clean sneakers or simple loafers, ankle socks and small studs or a friendship bracelet are plenty.
7. Athleta Girl Run Free Tank With Running Shorts
Hot practice days are where fabric choice matters most. A Run Free tank with loose, lined athletic shorts lets air move, and a bright tank against black, gray or navy keeps it sharp. Before buying, have her swing her arms: straps that slip off the shoulder will annoy her all practice. Lightweight running shoes, moisture-wicking socks and a sweat headband handle the heat, and a fitted sports top underneath adds coverage. Pack a zip hoodie in a drawstring bag, because sweaty kids get cold fast once they stop moving.
8. Athleta Girl High Neck Tee With Flare Leggings
Flare leggings bring back a retro shape that girls tend to love, and they pair well with a fitted high-neck tee. The hem is the thing to watch. Flares that drag under the heel fray and get soaked in puddles within a week, so I pick a length that just skims the top of the shoe. Chunky sneakers help here, lifting the hem and balancing the wider opening. White, berry, green or blue tees stand out against black flares. A cropped sweatshirt or light bomber covers cooler days, and a high waistband keeps a sport-length tee from riding up.
9. Athleta Girl Double Up Tee With Cargo Joggers
The Double Up tee already has two layers built in, so the styling job is mostly restraint. Keep colors simple, like a white and blue top over olive, tan or black cargo joggers, and let the layered construction be the detail. I'd choose cargos in a light, stretchy fabric with elastic cuffs; stiff canvas cargo pants add bulk and are hard to run in. Trail-style sneakers, a canvas backpack and a cap suit field trips and park days. Skip an oversized jacket on top, since the joggers already carry the volume, and reach for a slim zip jacket instead.
10. Athleta Girl Half Zip Hoodie With Leggings
In-between weather is when a half-zip hoodie earns its place. Over a thin fitted tee and supportive full-length leggings, it gives just enough warmth for a cool morning and comes off easily by lunch. Black leggings work with any hoodie color, while navy looks softer next to pale blue, pink or cream. Leaving the zip partly open shows the tee and stops the funnel neck from feeling bulky under her chin. Choose a backpack with room to stuff the hoodie in later, and pull long hair into a braid so it doesn't tangle in the collar.
11. Athleta Girl Crop Tank With High Rise Shorts
Parents ask me about crop tanks more than any other piece, and my answer is that the bottom matters more than the top. A crop tank looks age-appropriate when high-rise shorts with a wide waistband sit right up to its hem, leaving little or no gap. Shorts that are both low and loose are the real problem, because they slip during cartwheels and dance practice. An oversized button-front shirt or light zip hoodie covers her before and after class. Court sneakers, cushioned ankle socks and a belt bag for sunscreen finish it. Repeating two colors across the three pieces makes it look planned.
12. Athleta Girl Shimmer Top With Black Leggings
A subtle shimmer top is the party piece in an activewear drawer, and it works because everything around it stays plain. High-rise black leggings and a black zip hoodie let the shine do the talking. Feel the fabric before buying: metallic knits can be scratchy at the seams and underarms, and kids simply won't wear what itches. White or silver-trimmed sneakers echo the sheen. Small studs and a neat braid suit birthday parties and school events, and a slightly relaxed hoodie softens a fitted top.
13. Athleta Girl Seamless Top With Parachute Pants
Parachute pants are pure volume, so the top has to stay close to the body. A fitted, seam-free knit top in a bright color against black, stone, navy or olive pants gives the contrast that keeps this from looking sloppy. Use the toggles at the waist and ankles; left loose, the hems drag and the waist sags when she runs. Low-profile sneakers stop the whole silhouette from getting heavy at the feet. A cropped puffer vest or thin windbreaker covers chilly afternoons, and a crossbody bag and fabric headband are all the extras it needs. Never layer a second oversized shirt here.
14. Athleta Girl Blue Tee With Denim Shorts
Denim shorts take an athletic tee out of the gym and into a family day out. I look for shorts with a soft, stretchy waistband and enough length to sit cross-legged comfortably, since rigid kids' denim digs in. Medium wash flatters sky blue, turquoise or navy tees, and white sneakers keep it bright. A sport-length tee needs a higher rise; a relaxed tee can hang loose. Carry a striped sweatshirt or light jacket for air-conditioned spaces, and add a cap and a colorful backpack for outdoor plans where denim is allowed.
15. Athleta Girl White Tank With Printed Leggings
Printed leggings are easy to style once you stop trying to match them. A clean white tank lets the print lead; then I pull one color from the pattern into the sneakers, headband or jacket. Prints with two or three shades are far easier than busy ones. Do the bend test in the fitting room: cheaper printed leggings stretch thin and turn see-through over the seat when she touches her toes. A solid hoodie adds coverage between classes, and supportive trainers suit gymnastics or dance. The white tank later goes with shorts, skorts and joggers too.
16. Athleta Girl Graphic Tee With Track Pants
Graphic tees give kids a way to show personality, so I'd let her choose the motif and then build around it. Pull one color from the graphic into the track pants or shoes. Black track pants with a white side stripe are the most flexible, because the stripe creates a long, sporty line. The tee should sit at the hip; too long and it bunches when she sits on the floor in class. Classic sneakers, a zip hoodie and a roomy backpack complete it. Keep every other piece plain, and let a scrunchie or bracelet add color.
17. Athleta Girl Long Sleeve Top With Puffer Vest
A puffer vest keeps the core warm while leaving arms free to climb and throw, which is why I prefer it to a full coat for playground mornings. Layer it over a fitted long-sleeve top in cream, blue, green or berry, with a neutral vest in black, navy or stone. Smooth the sleeves before zipping, because bunched fabric at the armhole is uncomfortable all day. Full-length leggings or slim joggers and sturdy sneakers form the base. When the vest and bottoms share a color, the brighter top stands out. Add warm crew socks and a beanie for frosty days.
18. Athleta Girl Polo With Straight Leg Pants
Presentations, school concerts and uniform days call for something tidier, and a performance polo with pull-on straight-leg pants delivers it without stiff trousers. Stretch and a flat waistband matter here, because she may be sitting in a hall for an hour. White or pastel polos go with navy, khaki, charcoal or black. A full tuck looks traditional; a polo with a straight, vented hem can stay out. Simple loafers or clean low-top sneakers, ankle socks and a thin cardigan finish it. A headband or small studs are all the jewelry it needs.
19. Athleta Girl Crewneck Sweatshirt With Bike Shorts
Spring and early autumn days start cold and warm up by recess, which is exactly when a sweatshirt and bike shorts make sense. A roomy crewneck that reaches the hip, with fitted high-rise shorts beneath, is the oversize-over-fitted balance that never looks bulky. A thin tee underneath means the sweatshirt can come off later. If the sweatshirt is bright or has a graphic, keep the shorts a dark neutral. White crew socks and colorful running shoes add fun, and a cap and sunglasses ready it for camp or a playground visit.
20. Athleta Girl Layered Tank With Skort
Layering a tank over a fitted short-sleeve tee is an old trick for extra coverage, and kids like the color-block effect. Try white under blue, lavender under navy or pale pink under gray, with an athletic skort with built-in shorts. The base tee must fit closely, or it twists and bunches under the tank by midday. Court sneakers, ankle socks and a compact backpack make it school-to-play ready. On very hot days the tank can go solo where the setting allows, and a light jacket covers chilly air-conditioning. A ponytail or visor finishes it.
Washing Performance Knits So They Stay Fresh
Synthetic activewear is tough, but it hates two things: heat and fabric softener. Softener coats the fibers and stops them wicking sweat, and it can trap smells that a normal wash won't shift. High dryer heat breaks down the stretch fibers, which is why leggings go baggy at the knees and waistbands go wavy.
- Turn everything inside out. Sweat sits on the inside, and the printed or shimmer side is protected from rubbing.
- Zip hoodies and jackets closed before washing, so the teeth don't snag leggings and smooth knit tops.
- Wash cool with a regular detergent, and keep fleece away from smooth knits, since lint clings to them.
- Hang or lay flat to dry. If you must tumble dry, use the lowest setting and pull items out while slightly damp.
For tops that have started to smell even when clean, a soak in cool water with a splash of white vinegar before the wash usually helps. Wash practice clothes the same day if you can. A sweaty tank left balled up in a sports bag overnight is how odor sets into synthetic fibers in the first place.
What School Dress Codes Usually Check
Rules vary from school to school, so read your own handbook, but most codes look at the same few things: strap width on tanks, whether the midriff shows when standing, and the length of shorts and skorts. A tank over a fitted tee, a polo instead of a crop, or bike shorts under a skort handles most of those questions. I'd keep one dress-code-safe outfit ready for days when the weather and the rules disagree.
Start With the High-Rise Bottoms
If I were building a girl's activewear wardrobe from scratch, I'd buy the bottoms first: one pair of black leggings, high-rise bike shorts and a skort with real built-in shorts. Every tee, tank, polo and sweatshirt in this list attaches to those. Sport-length tops need the high rise, and sweatshirts need a fitted base. Supportive sneakers matter more than any accessory. Repeat one color somewhere and the outfit looks planned. Mostly, let her pick the colors, because the outfit she chose herself is the one she'll actually put on in the morning.
