One of the most common bra mistakes is washing them too frequently, so remember that you don't have to wash your bra every time you wear it. Instead, set up a rotation, and when one of your bras gets a little smelly or sweaty, it's time to wash. In other words, there are no set rules, but every three to five wears is a generally fair bet. Rotating your bras day by day also helps to preserve their elasticity, so it's a win-win.
