Okay, so I took a bit of a look at older S-E games and saw several hairstyles that I thought would look good in FFXIV (I also saw a few that were already in FFXIV), if tweaked a little bit. So here's a few (female) suggestions:

I particularly like Fran and Terra's wispy ponytails and the valkyries' long braids. I also saw a few male ones that would look good, but since I play a female character I concentrated on them for the moment. Anyone else have a previous S-E game with a hairstyle they like to be in FFXIV?
