Wasn't sure about coat being patent but having purchased was glad I chose it as it looks lovely on as sometimes black can be a bit draining on me but the patent made it look better suited to me. Got by usual size 14 which fitted perfectly. Lightweight coat which is warm. Bonus was that the hood was detachable which didn't realise until it came and also it was reduced which made it a great price. Originally posted on www.roman.co.uk
