These are jeans with a lot of stretch, and since they are thin, I think they are easy to wear even in the summer. They also have a leg-lengthening effect and are cool jeans. My son wore them a little, but his tastes changed, and they were stored in the closet. I did a home cleaning today for the listing. The size is M, but it's a 30. I have measured them, although it's amateur measurements, so please use them as a reference. Waist (flat): 39cm Front rise: 23.5cm Back rise: 33.5cm Inseam: 72.5cm Denim color: Blue
