This year the U.S. Open is being held in Southhampton, N.Y., an upscale seaside summer vacation spot packed with prestigious golf courses—like Shinnecock Hill Golf Course. With helicopters being the preferred mode of transportation and multi-million dollar homes on every corner, this isn't a flip flops and gym shorts kind of crowd. One golfer that won't have a problem fitting in with the locals is Justin Thomas. His Ralph Lauren scripting for the U.S. Open reads like a "How to Dress in the Hamptons" guide. It's a combination of soft summer pastels, classic navy sweaters and some quirky-yet-stylish chinos. Check out Thomas' looks for the week and where you can buy them. You may not summer in the Hamptons, but there's no reason you can't dress the part.
