The latest no-sweat style for fun in the sun is a one-piece playsuit. Selma Blair wore an Unhee design to MTV's TRL. "I always try to keep my pieces playful," says Unhee designer Suzy Yun. Blair gave the romper a 20's twist with Roger Vivier heels, but the piece would be equally effortless with flat sandals. "You throw it on and you're done," says Yun. "A romper just makes you feel like you're on vacation and playing, even if you're not."
