Why do you need a sports bra for small breasts? Breast tissue is a delicate material and without adequate support it will change. And even if your bust is smaller than average, you still need support and modesty cover. If you favor low to medium impact exercise activities like yoga, Pilates and jogging, a low to medium support sports bra will be fine. However, if you like to do aerobics, HIIT, CrossFit or running, then you should invest in a more supportive sports bra.
Sports bras for small breasts are usually ‘compression’ bras that work by holding your bust tight to the chest to prevent movement. They don’t have underwires and are mostly styled to look like a bralette or a cropped top. However, some, like the padded, Your Handful – Adjustable Sports Bra look more like an ordinary bra and are popular with breast cancer survivors.
HerStyleCode is constantly testing and reviewing the latest sports bras to identify those that aren’t worth buying and guide you towards the best short-list to choose from. Our teams are chosen from regular women, who wear a selection of bras for a minimum of two days, before reporting back on every aspect.
