Check out the suits these guys have on.
Not only is the one on the left wearing a double-breasted jacket – totally over the top for a casual fabric like seersucker, the one on the right is wearing a three-piece, with a club collar. If you’re going to try to emulate any one of these gents I’d say your best bet is the young one seated on the bottom left. Of course, it may just be that his hair is the one that looks the least 80’s so to my eye he looks better all around. I do like the argyle socks though.
Seersucker suits can’t be taken seriously unless you live in the very smallest of WASP pockets. Either don’t wear them at all, or wear them and know that you’re just having fun with your clothes.
