Welcome to The Essentials (opens in new tab), our weekly series highlighting a must-have classic, key to building a timeless, pulled-together closet.

One-piece swimsuits aren't relegated to the lap pool. With a reputation that's skewed matronly in the past, the maillot has been allotted new, modern sex appeal. A one-piece can make you a sultry Baywatch babe, all without the pitfalls of a twisted-up string bikini. Plunging necklines, swooping backs, and intricate strap details are just a few variations on the classic one-piece, giving butt-cheek baring two-pieces a dose of friendly competition. Built with a practical framework, the one-piece wins on beach days, and scores big on summer beach nights. Sport one with a breezy maxi skirt or pair it with a high-rise jean. Skeptics should envision themselves in an elegant one-shoulder version on the Italian Riviera or a gingham check for fireworks off a pier. There are so many options, you'll forget you ever owned a two-piece! Below, 13 to choose from.
