If you want to wear a feeling, of course, don't buckle it. Rambo was naked in the first drop of blood. But this depends on whether it is a commercial version or a military version. The commercial version is more suitable for China people's figure, and it can show a tall and straight figure when buckled; Military versions are all American versions, so it is best not to deduct them at home. During the war, the Taobao Brothers Military Company had a large collection of M65 trench coats made in the United States, as well as models. I recommend you to refer to them.
