To be honest YSL didn't really impress me too much this year. Though there are still elements you can take from this show. Obviously leather, grey, and black. Though you could also check out the fit of the coats, the trimming style with its unique cuts and the amazing shoes!
Even though this is borderline gothic chic, but not, since it's still very essentially French gentlemen. I feel that Raf Simons pulled off the "all black" look with Jil Sander so much better. However, I do love the leather pants, though all I can think of is Ross with his pair of leather pants in an episode of Friends. Baby powder with water anyone?
