Normally wear size L in Adidas but this was much too large and dint look a good fit. The jacket itself is gorgeous interms of colour, quality and style, nice chunky buttons and 2 side zip pockets they don't mention in the description which are very useful and secure. Returned in exchange for size M with the hope the fit is spot on, still waiting for delivery due to Christmas backlog I suspect. Overall would recommend but definitely size down, I'm 42/43 inch chest BTW.
