Great jacket, fit is what I would expect from a tailored fit, I am a 44 regular because of the shoulders, m luckily my stomach hasn't caught but the with rest of me yet. 5'10" 210lbs and the fit was great. Essentially similar to a 42 regular fit through the stomach with longer arms and broader shoulders. Gives the appearance of a tailored jacket without having to take it to the tailor. The material is nice, has a visible texture which is great for a suit jacket these days because it distinguishes it from a cheap polyester jacket with shiny uniform fabric.
