The Hamptons' chic-est Nosy Parker, Nolan really knows how to dress -- but his look is fairly simple for dudes to copy. A polo shirt with the collar popped (or better yet, two polos at once) and a pair of khakis gives you the foundation of Nolan's usual attire; up the resemblance with a seersucker blazer, and carry a binder with "NolCorp" printed on it. The hairstyle's trickier, but short-haired guys can brush in some temporary blond hair dye -- or buy a mop-top blond wig at the costume shop and tell everyone it's Nolan's first-season coif. Bonus points for a whale belt -- or hacking skills.
