Made from tsumugi fabric. I'm not sure of the material, but it doesn't seem to be 100% silk. It's a bit thick and sturdy, but lightweight. It feels rough to the touch, but I think it will be comfortable to wear. Machine washable at home (gentle cycle). Waist 62-110cm (elastic length 62cm) Hips 116cm Rise 35cm Inseam 68cm, long Ankle 40cm Front pockets Only the elastic length can be adjusted.
