I purchased this and only tried it on. It has a slim fit design that hugs the body's lines. There is a zipper and a slit in the back. Since there is no lining, the white side lines are see-through, so it seems like an inner layer would be a good idea. The size is 36 S. I think there is some slight stretch. I've inspected it myself and it seems there are no stains, but please forgive any oversights as I am not a professional. It will be shipped folded small via Nekopos.
