Note:   Various body parts need to be measured to allow a perfect fit of your jacket. However, the chest measurement is the most important one, especially if your body proportion can be considered to be “standard” (i.e. your arms are not longer than average). For a looser fit, you should add 1-2 inches to the chest measurement. Besides the chest, sleeve, shoulder and jacket length should also be measured. If you want to purchase a jacket for more casual events, you can choose a looser fitting than for formal events.
