A really lovely, practical little coat, that I have enjoyed wearing (just a few times) ... having a change now. It has a classic feel to it and looks good at both smart and casual events.... great with jeans + there's sufficient wool content to help keep you warm. The label states UK size 10. I'd say it is also spacious enough for a 12, though please do check measurements: Length, centre back, excluding collar: 32 ins, shoulder to shoulder: 16 ins, armpit to armpit: 19.5 ins and sleeve length from shoulder is: 23 ins.
