I believe this is a BALLET MANIACS sauna pants, size S. ● There was a long tag on the waist, but it was painful, so I cut it off. I don't remember the size, but I think it's S. It has a drawstring around the knees, which makes your legs look beautiful. Also, it has a design with different materials layered on top, which is very cute. Please refer to the photos. I purchased it directly from BALLET MANIACS. It's recommended for those who are worried about buying from overseas sites but want to wear cute items that are not the same as others. I have a huge amount of ballet wear, so I'm selling items that I don't wear anymore. This item has only been worn a few times.
