I didn’t know that it is not advisable to wash your bra after wearing because it can only do harm. Over washing the bra can only damage the support and elasticity of the bra. Wait for 3 or 4 days before you wash it depending on your activity. Let’s say if you are sweating the whole day, of course you need to wash it right away. Take off your bra when you are sleeping so to at least the bra can recover the shape and elasticity. Wash your bra with a gentler bra, but it you really want to wash it in a washing machine, choose a level to the most delicate cycle, or put your bra in bra mesh bag to avoid the damage in the latter.
