Long camel coatigan NWOT

Purchased recently from Amazon, size S, only tried on once. No tags on it. 100% Polyester Meant to fit oversized, but this is too big for me. I am generally a size XS to S depending on the brand. too big in the shoulders for me. Would work better for someone who is a small- medium, instead of an XS-S I think. See photos for the measurements. From a smoke free, pet free home.
