For a slimmer fit, choose a jacket size ~1″ smaller than your (body measurement) chest circumference. For a more relaxed, classic fit, choose the jacket size closest to your actual measured chest circumference.

Modern fit, also called a “tailored fit”, is a very popular cut, and for most men, it will be the default go-to. It occupies the middle ground between the looser “classic” fit and the ultra-sleek “slim fit.” To help you visualize this better, think of the iconic stock broker or banker look from the 1950s.

A slim jacket should feel snug, not tight. Even in a slim cut, you should be able to button the jacket without any effort.

The main difference between fitted and slim fit is fitted clothing is cut tighter around the torso than a slim fit. A fitted cut also solves the problem of the boxy slim cut by offering more shape to the body. As such, a fitted shirt is often cut with the curves and contours of the body in mind.
