When I got my jersey, selection was real low. They only had a white away that would fit me and it's an adult small. They are quite a bit bigger than most shirts you'd have, that's for sure, but yah, the sleeves do seem to be about the same.
I wanted a red vintage... but they only had one in XL which hung off of me like no other. Craziness. I'm going to get a name and # on the back of mine.
#73 :/)Haha, my kitten's named after him too.
