There’s a reason why barely-there bikinis have stuck around since they first made their way onto the scene in the 1980s. These skimpy bathing suits are not only sexy, but they’re also perfect for staying cool on the beach or poolside. But cheeky bikinis take things a step further. They have a higher, more narrow cut leg, which shows off a little more of your tush than a traditional two-piece would. Everything from slightly more modest bottoms to full-on thongs fit into this category, and, believe it or not, some of the trendiest cheeky bikinis are available on Amazon.
