Ever wonder what your favorite Project Runway hosts have on underneath? Well then this is the perfect video for you, in it the crew discusses what they wear underneath. Michael Kors says he wears boxerbriefs... black ones apparently. While Tim Gunn on the other hand can't make boxerbriefs work saying they ride up too much. Gunn prefers to go with the classic brief. Heidi keeps plugging the virtue of tight speedos on men, does this say anything about her husband Seal?
