Vineyard Vines may have started with neckties; but this summer they've launched a line of preppy-but-sexy bikinis that will keep you en vogue on Martha's Vineyard and beyond. We chose the Starfish and Ropes bandeau bikini. If you're going to get some sun, you can untie the straps and avoid pesky suntan lines. Don't forget to wear your sunscreen! Separates start at $55.
