It only makes sense that a guy who sings about finding great stuff in thrift shops, Grammy winner Macklemore, would be a guest judge on "Project Runway: Under the Gunn." On this week's episode (Thurs. March 13 at 9:00 p.m. on Lifetime), the rap sensation has some thoughts on what works and what doesn't. Trust the man who can pull off a second-hand fur, people!

Are you watching "Under the Gunn"? What do you think of Macklemore?
