Obvious title, though the pic is obvious. I kinda liked the sketch and decided to finish it: [link]
All the outfits are at least found in Colour Spreads, asides the bottom left (it's from a filler arc in the anime).
I REALLY want a shirt with his Jolly Roger on it (Centre shirt). Mayumi Tanaka was wearing one at the 2009 Jump Festa, so they are real (I just have no idea where to find one!) anyways, it's a cute shirt.
EDIT: Haha! Found said shirt in a Jump store in Osaka. SHIRT IS MINE!
