You've probably already thought to pack your cutest bikinis for your honeymoon, but you might not have thought about how useful a one-piece could be. If you're planning to do anything beyond lounging on the beach, you'll appreciate a one-piece for activities like snorkeling, hiking, and any other water sports. A suit like this one from JADE Swim is still plenty sexy — you just don't have to risk your top coming off at an inopportune time.
