The perfect fit of a dress shirt at the chest is a matter of personal preference. If you prefer a more relaxed fit, you can make the chest as large as you like. If you desire a tailored, slim look, you’ll want to reduce the Chest Width as much as possible without going so tight that it impacts comfort or produces unattractive pull lines across the chest.
How the measurement works
The Chest Width of the shirt is measured from the bottom of one armpit to another. Modifying the Chest Width by 1” adjusts the shirt circumference around your body by 2”.
