Funny, I've never been attracted to sharkskin, probably because there are so many bad examples of it out there.
Fabric is Dugdale (DP 3517), for anyone interested. It's a pretty light grey, but I'm happy with it. (It's somewhat similar to LL Mistral, which I know because Edwin and Matthew DeBoise had a jacket made up with the Mistral when they were tweaking the suit. They brought out the jacket for comparison.)
The tie is Cappelli.
Somewhat rhetorical for the thread: Do you have things in your closet that annoy you, but then you forget why they annoy you until you wear them again. And then you put them on an think, "I really don't like X," but you're stuck. Happened to me this morning with a shirt collar.
