Thin material, but surprisingly enough I bought the largest size just because Oriental made goods just are for tiny people, but the pants fit. This is about all I have to say about the pants. Buy their largest size then deal with the bagginess by taking them in when you receive your shipment--that is the only way to buy from these markets.I ordered an XL. This size is for a for the average woman it is foe an Asian womanI would order one size up. I usually wear a small. I bought a small and can wear it but its snug and waistband is tight. I really liked them so i ended up ordering a medium and its a perfect fit.Good fit,very comfortable.Fits good.Soft, light feel, very comfy but not very warm to wear in winter.If you have a butt already… these are a waste of money. They won’t make a difference.So don’t waste the moneyIncredibly comfy and soft
