Fashion Insider: One-piece swimsuits

One-piece swimsuits are all the rage — and for good reason. No longer are one pieces frumpy or for young children only. The latest styles feature cutout designs, beautiful back details and plunging necklines. There are even styles designed to shrink your waistline and make you look 10 pounds lighter. With summer in full swing and plenty of swim shops in town, Black Tie went on the hunt for a beach-perfect one piece.
