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. Aerie wants to help you out by giving you a free bottom with any bikini top purchase.
Just put a top and bottom in your cart (you can mix and match with style and size), and you’ll see the discount automatically. Plus, there’s free shipping and returns.
