Re: The X-men UNIFORM evolution on the sequel
I'm not sure they should go for the condom head look though. Captain America from the Avengers flick, Flash from the live action TV show shows that look is hard to translate to film.
Maybe visible hair, same collar-type from the previous X-men movies, or even a brown bomber jacket (same style Rogue wears in the Animated series/Cyclops has been shown to wear these circa Jim Lee-pencilled issues). And a more streamlined and futuristic Visor.
