This is a chest binder (B-holder) for cosplay. I tried it on over an undershirt, but the size didn't fit, so I'm selling it. Size: 55cm Underbust: 60-63cm With hooks and a zipper Has a pocket for a heat pack Straps can be attached Other notes: Although unused, it has been stored for a long time. Please understand that this is a used item before purchasing. I have a dog, so please be aware if you have allergies or are sensitive to such things. If you have any questions, please leave a comment.
