My favorite looks from Steven Alan's Spring 2011 Lookbook. I'll just go ahead and assume that Cam would pick the same looks as his favorite, too. Steven Alan's shirting is always spot on with a tailored fit. I haven't tried his shorts, but I'm sure it's spot on as well.
Mid-thigh shorts, bucks and sharp button-downs. Throw in a fedora and a bow-tie? Yes, please. You're speaking my language, Mr. Alan. Short shorts and bright colors.
