That grid has a lot of redundancies, really.
But, and this may not be favorite, more like ideal, Maybe the original BTAS Ivy >>88718960
but keeping her skin more plant-like, so a fusion of that Ivy, with the Arkahm Ivy.
Shit, throw in the nu52 outfit, since that and Katana's looks were the only thing I can remember liking about that costume change.
Wasn't Ivy's new costume able to grow some kind of moss? That's super practical in places with less green to control.
