Thanks. Not all 3-button jackets are meant to be 3/2 rolled. Lots of those suits you see sportscasters wearing are meant to be buttoned at the top — frankly, I think they look bad.
You might be able to have a jacket like that re-rolled/pressed into a 3/2 roll, but I’ve never tried or had someone try it for me. I just avoid wearing and buying such jackets.
