I was shopping down in Harajuku today and went to Richards amd Maris Rock. They had a fabulous hooded sweatshirt sale going on. They were marked off about 30% for all their different styles. They zip up the front (2 zipper pulls, so you can pull it up to fit over your hips or your petticoat), have zippers on the sleeves to make the sleeves wide or narrower, and a HUGE hood. Most of the hoods are square-shaped, so it looks sort of like cat ears or horns on top. Also, they are very warm because they are lined with fleese. There are many different styles; from cute alice-themed, to total goth, and everywhere in between. Besides being very cute, they also have a lot of sizes. Better yet, they run big. I wear a L in the US and I bought an M, and it still has a lot of room.
This is the sort of style they are, though most have a plain pattern (mostly black with some screen printing. Mine is black with white pinstripes and a crown screen print0 : http://id7.fm-p.jp/album/pub_view.php?dir=12&uid=marisrock&target=144&pub_num=0&user=0
