We’re more than familiar with the power of the little black dress. Think about it: Have you encountered an LBD that isn’t at once figure-flattering and fail-safe? We haven’t. Does it save you in a pinch time and time again? Yep, us, too. Well, the same goes for the LBD’s warm-weather counterpart, the little black swimsuit. Swimwear is often a tough fit, so when selecting a style, it’s important to choose one that you’ll feel comfortable in, highlights your assets and can hold its wear for more than a few seasons. Which is why we’re more than fanatical about black one-pieces and bikinis. Here, shop our edit to, um, suit your style—from full-coverage to sporty to fashion-forward.
