Why does Superman even wear a belt? His briefs about to fall down? Superman, in human interpretation, always looked a little fruity to me compared to most of his comic art images. Except the original Seigel-Schuster comics, he looked a little funny then, too.
George Reeves and Kirk Alyn looked as good as Chris Reeve in their time & place but even then Alyn could have laid off the Super-doughnuts a bit.
A 120 minute film has about 172,800 frames in it. About 5 or 6 test shots and out-take images aren't going to ruin it for me. I remember people complaining on the Internet about the X-men's costumes and the green Goblin Costume before the release of the respective films, and both of those franchises are gearing up for their 2nd sequels.
