To ensure that your new leather jacket arrives with the perfect fit, use this simple trick to choose the right size. Take an already perfectly fitting jacket out of your wardrobe and place it on a flat surface. Now take a tape measure and measure from one armpit to the other, as explained in the picture. Check the table below for the optimal size and compare it to the measurements you have just done. If you are still having trouble finding the right size don't hesitate to contact our customer service. We are more than happy to assist you and also answer any other questions or problems you might have.
