The difference between a sports bra and a bralette is the level of support they provide.
A sports bra is designed to minimize movement and stabilize your chest during activities where you're moving your body. Sports bras typically feature thick straps, compressive fabric, and high surface area to provide as much support as possible.
Bralettes, on the other hand, prioritize comfort and style over support. They are often made from soft, stretchy materials and feature minimal padding and structure. Bralettes are perfect for lounging or layering under sheer or low-cut tops, as they often have intricate details like lace trim or crisscross straps that add a touch of femininity. However, they may not provide enough support for larger busts or high-impact activities.
