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 s**y, 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.
