2. Everyday vs. sports bras
A survey of 200 women revealed most don't wear the same bra daily, with about a third washing theirs every two weeks. Some wash even less. This is doable with multiple bras in rotation, preserving their shape and avoiding overstretching.
Sports bras, however, need extra care. Soaked in sweat and moisture during exercise, they can become a hotspot for bacteria and smells. Washing sports bras after each workout is vital to keep them pristine and prolong their usability.
