Access Hollywood posed the question “what is it about a man in a kilt?” to the cast of Outlander and few of them had some rather colorful responses, while the whole kilt thing is lost on Tobias Menzies. The cast, executive producer Ronald D. Moore, and Diana Gabaldon also offered up some tips for wearing kilts. A few include having good calves and knees, swooping the kilt to sit (as demonstrated by Sam Heughan and Ronald D. Moore), and pairing it with a good pair of boots.
