Thanks for the comments guys. I am going to try and pull it off with confidence and some well matched pieces. I'll tailor it very slim if needed and add horn buttons. Maybe a fit pic when I'm doneMy proportions are really big - 6'7" with very broad shoulders/large drop and I like the aesthetic of wide lapels. That's partly the reason it caught my attention. I often wear fairly structured jackets to show some shape and detract from the ultra tall/skinny look which is a danger for me. When I get worried something is too adventurous I am often told I can get away with wearing anything because of my size... Not sure of the logic behind that though
I think this would look best on a man broad of shoulder or girth, given the lapels. I know this is debatable though.
