This is a Petit Bateau skirt. The waist is elastic, and the material is like a thin sweatshirt. I think it can be worn year-round. There is a faint stain in one place. Please check the third photo. Brand size: 10ans/140 Returns are not accepted. This is a used item, and the inspection is done by a private individual, so please refrain from purchasing if you are looking for a perfect item.
