I've owned a number of kilt jackets and "Saxon" tweed jackets over the years and they do vary quite a bit in how much padding the shoulders have. I suppose it's just a matter of personal preference.

I have one "Saxon" jacket that I feel has too much padding, but it does give the jacket, when I'm wearing it, a nice vintage look.

When was it, the 1940s? When that was the style. I don't know anything about vintage clothing (other than Highland things).
