BAM!!
Oversized pockets on a vintage dress shirt fabric.
It's the bastard child of a vintage sportswear jacket and an old Turnbull & Asser shirt.
The buttons I found on a pair of old U.S army underwear. They're totally cheap looking and matches the dressy fabric in a horrible but nice way.
It takes the dressy feeling out of it, so to speak..
Cool thing is you can wear it under a blazer and still look totally clean and crisp but anyone paying attention to detail will note the huge pocket and think "That dude has no fucking clue, or, he's way cooler than me"
(Except for any Japanese guy, who will realize it's really cool right away)
