I thought this was Anka's costume?
I will just say I would agree that if they are going with second generation inheritor of one of the founders of mutant kind's vision they need something more like one would expect a warrior to wear. Out of her three main green number outfits its basically her original or Genosha without the warrior vibe to it and much more monochromatic. I am not sure silver works as a good secondary color for Lorna though. Gold, black and purple contrast the green better also one of the things that worked on her Genosha design was shoulder pads.
