The length of the jacket is fine and is not too short. Bd22 is correct that the pants have to be hemmed that short when they are that narrow but, for what it's worth, the length doesn't look that bad. In regards to the bunching in the seat, does it correct when you pull up your pants in the back? Then I've read that means the belt line has to be lowered in the back. Apparently, it's not too difficult for a good tailor to do. However, you would then need to rehem the pants.
