Very Steed-y. I've been watching the Avengers, and he often has flap breast pockets.
I bet the bespeaker of the eBay suit had Steed as an influence, so I can fault him only so much, but the suit gilds the lilly. Velvet collar, flapped breast pocket, ticket pocket, hacking pockets, turnback cuffs and patterned cloth?
If it were just a sportcoat, I'd like it more. But boy, there's a lot going on.
