I find this to be the least offensive of the go shirts because the five on it is fairly small and there's nothing else really odd about it. I wouldn't even have noticed this shirt if he didn't ALWAYS WEAR SHIRTS WITH THE NUMBER FIVE ON THEM.

Ogata for once appears without his White Pimpsuit(tm), and somehow manages to find a shirt with the ugliest paisley I have ever seen on a male in manga. I'm pretty sure I've seen this exact screentone used for lace on big fancy dresses in shoujo manga. It's not kosher on a guy's shirt.

Yet again Akira manages to wear long pants, but his sleeves suffer because of it. He probably developed this tendancy to mangle his clothing as a way to work out his issues with his father. Or he's just gay.
volume 5, page 50
I scanned this initially because yet again Hikaru is wearing tights with his shorts. But looking at it again, it's a pretty bad combination and I dread to think of what it would look like in color. Not only are there the tights, but the shorts have some obscene pattern on them, and I'm guessing the shirt probably doesn't match either of them.

The problem with this is it has a fruity zipper up the front, but the visible five is on the back. So it's fruity in the front, but follows the bad pun pattern on the back.

You remember Akota-san and his toupee from volume one? Well he comes back in volume five, sans toupee, but he's dressin' like a homeboy. This picture pretty much speaks for me, adding anything would be redundant.

Kishimoto managed to avoid doing anything too horribly wrong because he only showed up in his school uniform. Until this shirt. It has big shiny elbow patches much like your elderly literature professor's sports jacket! If Kishimoto lost the patches it really wouldn't be so bad, but Obata likes to make things look weird.

This is a crime against camoflage. The military needs to hunt Waya down for this and burn it. I'm not sure how one makes a sweater with a camoflage pattern, but Waya found one, and worse yet, it has a big star right in the middle of the chest. I'm guessing this article of clothing was rejected by the chinese communist army some time in the 1950's and it landed in Waya's closet.

This would be a nice sane shirt in a world of fashion disasters had Obata NOT FELT IT NECESSARY TO PUT A FIVE ON IT. I quit laughing at these a long time ago. I'm not even amused, I just roll my eyes.
volume 6, page 52
This is special, not only does it fulfill the visual pun requirement Obata apparently has for Hikaru's wardrobe, but it seems to have a built in bondage collar. There is no hood on it, just a high neck with laces on it. I can think of no other purpose for such a collar than bondage.
volume 6, page 65
This whole thing is pretty much WTF. First it has the stupidest fastenings since Akari's toggle skirt. Then it has the most random seams, with piping along them. And finally, while it is apparently white, the Kaio winter uniform proved that we don't actually know what color it could be, and for all we know it might be a lovely rose pink. Akira, you need help, badly.
volume 6, page 89
Akira managed to stop mangling his sleeves, but the shorts have made a reappearance. And this time he's taken a page from Hikaru's book and is wearing tights with them, for the fruitiest combination he's ever worn. Puu actually thought we needed a new rating on the gay-o-meter for this outfit. Too bad, we don't get one. Just imagine there's a higher rating than "FLAMING!"

Isumi thus far managed to wear only rather boring dress shirts and need his hair trimmed. But this cardigan makes it obvious that his grandmother dresses him. I could see a girl wearing something like this to flaunt her chest. Isumi is a guy though, and this is the wrong way to flaunt chest, if that is his goal.
