This look is actually more difficult to pull off than it looks? A slight gym body is requires and a good grooming regime. The beany should be good quality and large and slouchy. Try All Saint or D Squared for accessories and keep the rest of the look slightly distressed to avoid looking too try-hard and make sure you smell good enough to eat! x
I almost want to describe this as a very “well-tailored casual” look but to call it tailored doesn’t seem right. It is not tailored but just “well-proportioned” or “well-fitted” The jacket length is good, the sleeve lengths are good (if not a little fashion-forward) and the jeans are slim but not tight. So often we call casual is actually just sloppy. This takes “casual” to higher level.
