What the AI looks for in Girls' Sports Clothing
- Fabric
- Polyester or nylon blended with spandex for training pieces; avoid all-cotton for sweaty sports Cotton holds sweat, gets heavy and chafes, while synthetics wick and dry fast.
- Legging opacity
- Should stay opaque in a deep squat under bright light Thin leggings turn see-through when stretched, the most common complaint in girls' activewear.
- Sizing system
- Girls' sizes are typically labelled XS to XL (or YXS to YXL) and run by height and weight, not age Age labels are unreliable, and girls' cuts differ from women's in rise and chest.
- Seams and waistband
- Flat or flatlock seams and a wide, covered elastic waistband Raised seams chafe under repetitive movement, and narrow exposed elastic rolls and digs in.
- Short inseam
- Match the inseam to the sport: short and snug for volleyball and gymnastics, longer and looser for running or soccer The wrong length either rides up or restricts movement.
- Sun protection
- Look for a stated UPF rating on tops worn for long outdoor sessions A UPF label is a tested claim, whereas a thin tee may let through much more UV.
Brands that matter
- Under Armour: Broad girls' range, from Tech tees to HeatGear and ColdGear layers.
- Nike: Strong in Dri-FIT tops and Nike Pro shorts and leggings.
- adidas: Solid girls' training basics and three-stripe leggings.
- Champion: Lower-cost basics for casual and PE use.
- Puma: Affordable girls' training sets and leggings.
What to avoid
- Cotton tees and shorts for sweaty or hot-weather sports
- Thin, shiny leggings that turn sheer when stretched
- Buying several sizes up 'to grow into' compression or fitted pieces, which lose their function when loose
- Decorative trim, glitter prints or tags that scratch during movement
Questions
Should a tween wear girls' or women's sizes?
Stay in girls' sizing until she outgrows the largest size by height, then move to women's XS or S, which have a longer rise and more room in the chest and hips.
Do girls need a sports bra for sport?
Once breast development begins, a soft girls' sports bra or crop top cuts down on discomfort and self-consciousness. Fit by band and comfort, not age.
