Garage ultra fleece barrel leg sweatpants

Size: XS (the waistband is tighter than other garage sweats) Color: pearl melange (very close to light grey, as shown in the 4th pic, the first three model pics from garage websites are kinda misleading) High rise fit, barrel leg Only worn twice, but after my last wear, I noticed there are two dot stains on the back that cannot be washed off. I have no idea where they’re from. Other than this, it’s in perfect condition.
