Last summer I watched a guy in cargo shorts, white tube socks, and a faded concert tee try to take his wife out to a beachfront dinner. She wasn't happy. He wasn't comfortable. And honestly, neither was anyone else at the table. The beach is one of the trickiest places for a man to dress. The dress code shifts every two hours — morning swim, lunch on the boardwalk, an afternoon walk, sunset cocktails, dinner with the in-laws. Most guys pack one swimsuit and three t-shirts and hope for the best.
