that's a japan only shirt, of course it has a loop tag.
aite chill, but are there any other signs of authenticity or fakenticity?
I thought the tags were perforated and I can't see that on the pictures.
I'd be wary, but maybe someone else could correct me on the tag/label.
Also, if it were a legit piece surely it would have a higher starting bid/reserve. He's sold some other supreme Ts dirt cheap whilst other Ts have gone for ~£80. I'm not sure what to make of it, but that's just my opinion - I'd leave it.
