Can i get 1 size smaller jacket to make it look fitted?

if i get a jacket a size smaller will it look better ? im getting one of those 80s leather biker jackets off the internet and was wondering if i got a size smaller it would look better because those jackets have really bulky shoulders. im a size 36 and my chest measurements are about 35 inches. if i get a size 34 jacket, would it be way to small or would it fit better than the 36 ?
