These are thin denim bloomers. The leg openings have elastic in the back. I can't find a size label, but they feel like they would fit an 80-90 cm size. There is some fading characteristic of denim due to age, but I hope you can appreciate that as part of the charm. The elastic in the waist and elsewhere is not broken, but since these are quite old, I recommend replacing the elastic. Type: Denim pants Design: Solid
