I have a 184 SM regular size 46 (not long) that does not really have a tight waistband and I wish it did. The waist band seems to be nearly as wide as the leather jacket itself and instead of pulling in the bottom of the jacket, it just seems to be a knitted skirt around the edge of the leather without creating that necessary pull that makes gives it that bottleneck look. I like the jacket and this is my third Schott 184SM, but I have the feeling that the Long version might do a better job of providing a tight waistband at the bottom of the jacket. The regular size jacket is a very short jacket and without that really tight waistband, it can easily end up looking like a leather lampshade.
