Re: Boy, those uniforms must bunch up very easily or something...
Never having been forced to wear skin-tight spandex, I've always wondered... specifically what was it about the S1 & S2 uniforms that caused back pain for the actors? Supposedly that was a common complaint that was alleviated with the S3 uniforms. I can't understand how clothing alone can cause back pain (unless it's really heavy or something like that).
I suspect it'd have something to do with always having to keep your bag tight and tense to stand up straight against the strain of the spandex trying to constrict you.
Just because it's futuristic doesn't mean it's practical.
