Tim Gunn In High School (WATCH)

When Tim Gunn, fashion expert and host of the TV series "Project Runway", joined me on Mondays with Marlo I just had to ask him what he was like in high school and what he wore to his prom. Although he said he didn't go to his prom, he did reveal that in high school he was extraordinarily shy! Not only did he say that he was an introverted kid, but he was also very proud to be a geek.
