Yeah, definitely. I was watching the special features for Iron Man 2 the other night and there were a number of scenes that were shot with RDJ and Don Cheadle wearing only the pieces of the suit from the waist up, and they looked incredibly silly. I mean, they could just barely move around even just wearing those upper pieces of lightweight fiberglass armor, and any little movement created huge gaps and spaces between all the different pieces. You quickly get the overwhelming impression that no person, ever, could actually fit into a real working rigid metal suit like that and move around in even the slightest. So for people who thinks this looks unrealistic because it *might* have a narrower waist---that should be the very least of your concerns on realism.
