(msn) When it comes to bathing suits, less isn't necessarily more. Ditch your previous notions of the one-piece swimsuit as a conservative beach garment — recent runways have been red-hot with reinvented versions of this sizzling style. From iconic images of Farrah Fawcett and Bo Derek to a modern design as seen on Katie Holmes, the fashion-forward one-piece can be sexier than a bikini. Just like the little black dress, the "LBBS" is a classic that every woman should own. Understated yet chic, a black one-piece is sexy in a subtle way. It's sleek and streamlined, sophisticated and saucy — a must-have no matter what your shape or size. And though it may not be splashy, this simple suit can be accessorized and re-worn in so many different ways, you'll never need to pack a second swimsuit for vacation. Plus, there are so many different styles to choose from, it's easy to experiment and find the perfect one for you.
