I saw Tim Gunn speak at the Library of Congress on Tuesday. He spoke about growing up in DC, his career path and filming Project Runway. Because the event was part of a series about disco fashion, there was a lot of talk about fashion faux pas. I was appalled that he called out leggings (my weekend go-to) as one of his most-hated trends. “They’re not pants, they’re undergarments!” I was prepared to donate them to Goodwill, but my friends talked me off the ledge.
