Following up some old discussions about proper A2 fit I would like to add some more insights from my perspective to this discussion. In my eyes an A2 has never been a fashion item. It was ment to be purely functional which especially includes the function to move within them. It should neither bother you nor should it inhibit your movement. If you look on old fotos from WWII you can see that many crews had chosen pretty relaxed fitting A2 jackets even late during the war. Here are some examples from 1941 to 1944:
Lieutenant Dick Winters, 101st airborne, in 1942, wearing a relaxed fitting Dubow A2:
Here is a war photo of the crew of the famous witchcraft B24 bomber in December 1944 with pretty relaxed fitting A2s:
This is the graduation class of Sikeston Airschool, December 1941, with relaxed fitting jackets. Chapman from Goodwear Leather uses this even as example for proper A2 fit:
I think these examples show that many warriors preferred relaxed fitting A2s for functional reasons. And that is the exact reason how we chose the size of an A2 today: For function, not for fashion
