Prioritize proper fit

Choose a size that provides light compression without digging in; adjustable straps and stretch fabrics improve fit for growing bodies

Consider back style for range of motion

Strappy or racerback designs allow better shoulder mobility for sports like volleyball and dance

Check fabric and care

Moisture-wicking, stretchy blends that list easy-care instructions keep bras fresh and durable through frequent washes

Balance support and comfort
