It’s a stretchy material. If you’re skinny and I mean like 100lbs typa skinny get a xs it will fit. The material isn’t sheer but it definitely does fit nice tho and it’s comfortable to move around in , it’s thin in a good way , it’s breathable not thin to a point where u can see you’re panties but tho I recommend this

Perfect for airport travel and quick runs. Not thick enough for winter but a nice sporty fall piece

I’m glad it did stretch to fit me but because of how much it needed to stretch it became sheer. I normally wear XL but that size wasn’t even an option so I risked getting an L, for my thick woman out there it does stretch and it is comfy I liked it but maybe only for a picture because it’s sheer from the butt area. Maybe trying a skin color spandex under to cover up the fact that you can see your underwear. It does have a lot of potential it just so happens that in my case this didn’t quite go as I hoped b
