#24 Lazaro Hernandez and Jack McCollough—180
WHAT: Designers, Proenza Schouler
WHY: Because Lazaro Hernandez and Jack McCollough are the new guard of American fashion. Since launching their line in 2002, they've dressed all the coolest girls from Kate Bosworth to Vanessa Traina, and their interpretation of youthful modern luxury is the epitome of cool. Extra points for designing the PS1, the It-Bag for our generation.
