A corduroy suit ,like this one from Domenico Vacca, is a great option for Fall/Winter. I've seen so many, too many actually, super 100's , 450's and ultra 6000's that I'm looking for a fabric with a little more body, and little more chunk, a little more tweedy.
I love the suit Clark Gable is wore in "It Happened One Night"
I've been on an old movie kick lately and those heavy-in-the-hand fabrics from the 20's and 30's look so fresh to me again.
