Very long hairstyle. We've got lots of short or semi-long hairstyle, but I'm asking for something covering the entire back and to the buttock. And, it's possible to get it with fan-made mods, so if the fans are able to make it, I don't see why SE won't be able to do it. Yes sometime the animation can be weird with some piece of armor, I'll give that, but, you just need to look at the Regalia and how bad it is with building, trees and everything, and still, it's there and people (who like to have a futurist car in a medieval-ish universe, incompatible with the lore) still enjoy it. So I personally won't mind some issues with some armor, in fact some hairstyle already have trouble with some piece of gear, but with all the glamour available in the game, there is a way to make it works...
