Ladies stylish fully-lined suede jacket - RIVER ISLAND - black - buttons. Label size Medium - I'd say UK 14-16. I measured 22" armpit to armpit.  28" length. 17" shoulder to shoulder. 24" shoulder to cuff. I would say a fitted UK 16 - more roomy UK 14. 100% suede. It's lightweight and very soft and supple so a bit of a cross with a shirt (think heavy, lumberjack shirt). It's quite a masculine (unfitted) cut so probably looks best oversized. Lightly worn - distress suits the styling - very comfortable.
