Going to weddings is fun, but it can be hard on the wallet. Especially if you buy something new for every invite you receive. Before you know it, you'll need a whole 'nother closet for storage (good luck with that), and end up with a bunch of stuff you might never wear again. But, we believe one awesome, adaptable frock is all you need. Yes, one . Beach, ballroom, or dive bar, every wedding you go to is a little bit different. And, the trick to making a great impression — and the most of your hard-earned money — is to know how to adapt what you already have. Ahead, we found one frock that can deliver at least three times over.
