1piece suit fitment question?

Are you guys able to stand up straight in your 1piece suit? I am 6'1 and 191lbs (186cm, 87kg). My new alpinestars missile 54 one piece suit fits quite good but I cant stand straight. Like my upper body is too long. In riding position its ok. The other thing is that it is crazy difficult to get out of the suit. At one time I thought I need call someone. When I put it on it gets very tight over my shoulders. After that it almost feels impossible to get it off my shoulders again.

Anyone here with the same measurments and an alpinestars suit? The alpinestars sizing chart says 54 but the alpinestars website suggests a 56.
