The choice of a belt back was because I like the style. I've got a few early 30s, 40s and 70s belt backs and I wanted to emulate the style. I don't think the center vent is very high, I think it might be the angle the picture was taken but I could be wrong. I re-took the back and front pictures to include my whole body. It gives better context than a close up shot of the jacket in a low angle.
