Like some of you have already mentioned, there's definetly a new material and texture that studios and designers are starting to use for movie costumes, as we can see:
personally, I wouldnt mind if Singer and her designer tried costumes for original actors with this texture but giving them more volume and a second texture, like on First Class.
They could easily give us comic inspired costumes for characters like Rogue, Cyclops, Colossus or even Wolverine.
