I've just remade this jacket that
I bought at second-hand shop around my place, with studs got at KILLERS at 下北沢Shimokitazawa.
It didn't need so much time
to do it, it's had about 2weeks,
put 40~50 studs on its both shoulders and around arms.
I don't know should I put more studs on it or paint something on its back yet, but I have time to think for it.
Anyway, you never think this jack was sold only 100yen at the shop, don't you? haha ;)
