Unisex M size It's about the equivalent of a men's M size, or a women's L size. Women can wear it a bit loose. I bought it at Disneyland. I've worn it twice, and it's still in good condition. It seems to be a commemorative hoodie that was sold right after the Monsters, Inc. attraction opened. It's no longer sold, so how about it if you like it? ^^ Thank you for looking.
