Customer service was so helpful. I initially ordered a size I thought would fit, but I’m glad I emailed the next morning because they helped me find the size I needed, and it was perfect!!! The sizing chart was a bit confusing to me because from the measurements I took, I thought I needed a 2XL, but apparently needed a 4XL. I couldn’t be more pleased with the service and quality of the jacket. They even included my request to add a zippered lining. Thank you so much! I can’t wait for my son to see his letterman jacket!
