We recommend having at least five bras in your wardrobe. The number of bras you should have depends on how frequently you wear them and the occasions you need them for. For example, in addition to the everyday bras you wear with regular clothing, you might need a specialized bra for working out and a bra you can wear with strapless formalwear. Having more bras extends the lifespan of your bras because they get worn less frequently, and it also allows you to wait longer between washes because you have clean options you can rotate in.
