NWT Nine West ‘Alec Boyfriend’ Destroyed Jeans

Super cute and brand new, never worn, Nine West Alec Boyfriend Ankle Destroyed look jeans. I’ve never worn these but they have been hanging in my closet for a bit and when taking pics I noticed a spot on the back of one leg that I’m not sure what it is. It almost looks like dust but I can’t seem to get it off. It’s barely noticeable tho. Please see last pic.
