Taylor Swift Authentic Red Cardigan

Authentic cardigan for Taylor swifts red album Size XL/XXL Super cute and cozy, selling because I originally ordered two in different sizes and i realistically don’t need two of the same cardigans for myself I’ve worn this cardigan a few times, there is a mark on the back, I’ve shown in the photo. I haven’t personally tried cleaning the stain off as I’m not sure what the best way to go about it is so not sure if it’s a stubborn stain or not. In my option the stain isn’t that noticeable especially because it’s in the back of the cardigan. Any wear is shown in the photos, if you need more photos please ask and I’ll take more :)
