Vintage Tyber Vintage Faux Fur Coat UK SIZING

Please see items description in picture above. I recently purchased this through a different site, shipped directly from the UK. The coat is lovely, however, it doesn’t fit me. This is a UK size 10-12, US is equivalent to a 6-8. Midnight blue (so pretty). As indicated, the armpits of the lining are ripped but can be easily repaired in my opinion.
