How to choose a suit.
Shoulders.
A proper and naturally snug shoulder fit ensures the jacket is right.
Chest.
A jacket should button up easily with some room left inside for comfort and ease.
Length.
The hem should sit only an inch or two below your cuff.
Sleeves.
A cuff should line up to where the base of your thumb meets your wrist.
Trousers.
Tight or loose, the pant rise is your personal preference for style and comfort.
