It's a movie. The whole thing is a lie--Andrew and Toby can't leap through the air and swing on webs either--even if they had proper webbing the forces involved would rip their arms out of their sockets. It doesn't matter. The point is to make the fantasy work in a smooth and sleek way on screen, in the context of the movie's world. The costume designer's jobs are to make the suit look as best as it can look in each scenario as per the needs of the script. The suit is a fantasy like any other part of the movie. If Andrew's lips would normally show through the mask where it droops against his face, it doesn't matter, he needs to look like Spider-Man when he wears the suit, so they use a faceshell so that the suit looks as best as it can be. If normally there would be a gap on his neck because of the fabric layering over itself, it doesn't matter, it needs to look like a seamless suit, so they build it with an attached mask. The suit needs to look the best that it can look in every scenario. This is how movies work. They're not going to show Andrew taking 20 minutes to struggle with the back zippers while wiggling into the suit either. They are going to show him duck out of sight for a second and then charge on screen in full suited glory, because it makes the story better. The unrealistic suit makes the movie work a little better.
Honestly mate, these things are not real. I thought we went over this when you didn't understand why muscles don't pop through the spandex like the way the comic books are drawn.
