These are Brand New. I bought them and put them in the closet but lost weight before I had a chance to wear them. These are a polyester/Spandex blend. As an xl goes I would say they run large. 16” so 32 laying flat unstretched. I did a reasonable stretch on them to 21” they would stretch more. I stretched the waist to wear the bottom was not stretching out. Reasonably I would say they’d fit a 16/18 women’s. These are incredibly slimming when worn. Any questions feel free to ask. I have a ton of clothes that need to go between a 12-18. Most of which were barely worn. A lot maybe 1-2 times. I’ll try to be honest in descriptions. I dropped a lot of weight in the past year. Non smoking, pet friendly home. Everything I am listing was my own. So feel free to ask any questions,
