No one will suggest you a derby that will go with anything, but Guidi should go with many things (including some casual suits). CCP and Augusta as well. 10 Sei 0 Otto has some decent offerings from time to time. My personal favorites are Layer 0 but they will definitely not go with anything.
Men in Kilt look great. Sean Connery rocks it, Axl Rose looked good too and the guy whose pic was posted earlier - this one:
looks pretty good as well. I would freakin wear a kilt if I could pull it off. But kilts are not skirts.
