One of this biggest problems with buying bikinis, besides finding the right size, is having to buy two separate things. Even with affordable swimsuits, you wind up spending $50+ on two small pieces of fabric. But right now, Aerie is marking down a ton of bikini tops and bottoms to $20 and under, which means you can get a full bathing suit for the price of one piece.
