It's relatively trim fitting so I ordered one size up (normally I'm a 46 and I went with a 48). The back length is not overly long; it's a true waist length jacket even in a size up. The sleeves are trim, not loose or blousey. Best thing is the grain and patina. A really nice hide, reminiscent of older, vintage goatskin G-1's.
I highly recommend this jacket.
