I splurged on this jean jacket hoping it would be the only one I'd ever need and it probably is. The material feels really nice- extremely durable but also pretty lightweight, and it's surprisingly warm / insulating too. I bought a medium because the model was the same height as me (though maybe 20 pounds lighter) and it fits pretty well, 8/10. The stomach is a little too roomy and the sleeves ride up a tiny bit too much in certain positions, but mostly I like the loose fit and how the model wears it is very representative of what it is (a loose, comfortable jacket) vs. what it is not (a slim, form fitting jacket). It's very casual feeling and it fits great wearing a sweater or hoodie under it, or just a T-shirt.
