This is a sleeveless hoodie from Black Machine. I purchased it about 7 years ago at the Nubian Harajuku store. It's a model that came out during the peak of the luxury street style trend. I've worn it twice. It's oversized, so the sleeves reach about the elbows. The size is 2, which is about a Large. It has a drawstring inside so you can cinch it. *Please feel free to ask any questions in the comments. I'm also open to price negotiations.
