Used a few times, the elastic in the waist is stretched out. Shows signs of wear. I didn't use it at all last year. The ankle ribbing makes it very easy to wear, light, and warm. I think it would be suitable to wear under pajamas. I plan to ship via Mercari Takkyubin. Waist is 84cm when stretched. Inseam is 63cm. I am extremely busy, so please refrain from purchasing if you are in a hurry.
