How to Measure
Chest:
The chest is a key area for jacket sizing. To get an accurate measurement, stand up straight and keep your arms relaxed at your sides. Ideally, have someone help you by wrapping a tape measure around your chest. Ensure there's a bit of extra space—about an inch—so you can move comfortably.
Leather/Denim Jacket Chest measurement: Given the characteristics of the fabric, leather and denim jackets do not offer any stretch. If you prefer a more comfortable fit and want to avoid a snug feel, it's advisable to choose the next larger size.
Sleeve:
To measure your sleeve length, start at the center of the back of your neck. From there, run the measuring tape over your shoulder and down the length of your arm to your wrist.
Waist:
Waist measurement: The waist is measured in the same way as described above for the chest but around your waist.
Between Sizes?
If your measurements fall between sizes on the chart, it's best to select the next larger size for a more comfortable fit.
