Labelled size 10 USA. Usually you add 4 to get the UK size equivalent, which would make this a UK 14. Pit to pit measures 19 inches, shoulder to hem 27 inches. Note, this is quite a longline jacket. Best to measure a current garment of your own in a similar style to make sure this blazer is the right fit for you.

Not in fantastic condition: several small holes/nicks/pulls, one button missing, some sun-fading to the shoulders and sleeves.
