Method #1
Take a tape measure and measure your chest at the widest point (in inches). Half this and this will be your CHEST ACROSS. For BACK LENGTH, measure from the nape of your neck to the bottom of your hips. SLEEVE LENGTH should be measured from the very top of your shoulder to the wrist bone. To measure SHOULDERS ACROSS, place the tape measure from the very outer edge of one shoulder to the other.
Method #2
Take an existing jacket from your own collection that fits you perfectly. Lay it flat and zip it all the way up. Use a tape measure to measure the chest across from pit to pit. Measure the full sleeve length from the top of the shoulder down to the bottom of the cuff. Then measure the shoulder with from one side to the other. Finally, flip the jacket over and measure the back length from just under the collar to the bottom hem.
Once you have made a note of your measurements, refer back to our sizing chart above to see which size would best fit you.
