Khaki shorts from an outlet somewhere, Soludos espadrilles, and a J. Crew Breton-style T-shirt. It's hard to work around the mass of khaki and cream, but I felt like the shoes brought it all together well enough to leave the house.
But seriously, you need a pair of espadrilles for the summer. They are cheap, durable, and not flip flops. I now own another pair in a cream color.
