In celebration of National Hat Day, we’ve selected our favorite celebs wearing hats by legendary hat designer, Philip Treacy. Treacy has outfitted some of the biggest celebs in the fashion world and has collaborated with Moet, Project Runway and Mercedes Benz. His designs are so avant-garde, Lady Gaga submitted her resume to Treacy for an internship position! Here are the hats that we want to wear today. Which hat is your favorite (or least favorite)?
