Thanks mate. I need to shorten the sleeves an inch, but the jacket fit is perfect in person.
I tried on the 46, 48 and 50 and went with the 48 as the 46 was much too tight across the chest.
It was nice to buy something in person for a change and try it on in multiple sizes. :)
The zip is off center on this jacket and it's like a double breasted blazer, so it is 'billowy' when open.
