Research involving 200 women revealed that most avoid wearing identical bras daily, with approximately one-third washing their bras biweekly. Others clean them less frequently. This works when owning multiple bras for rotation, maintaining their form and preventing excessive stretching.
Athletic bras demand greater care. Since they encounter sweat and dampness during physical activity, they can collect bacteria and produce odors. Washing sports bras after each workout session is crucial for cleanliness and longevity.
