Nasty Gal Pink Suede Boots

Bought from Nasty Gal for New Years a couple years ago and only wore them once. I’m a clutz which is why there is some minor staining and a scratch on the heel (pictured.) I think if I used Dawn soap and a good brush I could get it off but I haven’t yet! They don’t say what size they are but I wear a 7.5 normally!
