This is a Nano Universe setup. The pants have an adjustable drawstring waist with elastic, so they should be comfortable to wear. I bought it on Mercari, but the pants didn't fit, so I wore them 4-5 times and then had them dry cleaned and stored. There are no noticeable stains or scratches, but it is still a used item, so please only purchase if you understand this. Dry cleaned. Season: Spring, Autumn, Winter Color: Olive Size: M Material: Polyester Waist: 72cm, Thigh width: 26cm, Inseam: 66cm Nano Universe
