Alazzo Clothing teaches the viewer how to measure their jacket length. You'll need a flexible measuring tape first. First, put your measuring tape at the point where the shoulder and neck seams meet. From this point, you will measure down to the length desired. Measure down the front of the chest and not the back. The length you will measure will end right around where your thumb joint is. Record this amount in inches and this is your jacket length! Take this number in and get jackets tailored and fit to your needs. Throughout the process, make sure you are standing up straight and high.
