If there is indeed a fashion rulebook, it’s likely that rule #2 or #3 would reinforce the fact that accessories are key. Find the slightest glimmer of sun on the horizon and try to catch any self-respecting diva without a pair of designer shades to hide her face. Or any hipster sans Ray-Bans. Stock up on everything from Puma to this season’s Prada. You’ll see the world in a whole new light.
