We don’t need any more convincing that a simple black one-piece is the sexiest suit you can own. The style keeps everything in tight, it goes with just about any cover-up you’ve got, and with a deep plunging neckline like Hailee Steinfeld’s, it can be quite alluring too. It’s not just her ridiculously flattering bathing suit we’ve got eyes on, but her easy high-fashion accessories. A pair of Miu Miu cat eye sunglasses and and a few braided bracelets and you’re more than ready to hit the beach — in Miami like Hailee, or just about anywhere else in the world. Read on to get inspired, then shop the look.
