The only thing I can't stand about character design (anywhere) is when the dress doesn't combine with the character's behaviour. For instance Ashe wears a miniskirt that would be sure to ride up her ass as soon as she takes a step, which means no sane woman would put it on and then go fight monsters or walk around town. Lulu's dress is aesthetically awesome but combined with the size of her boobs is impossible because it'd never stay up if she runs, jumps, dodges or moves in some other way. Etc.
One thing that WAS awesome about Ashe though was that Yoshida clearly drew inspiration for her outfit from Agrias, which was a pretty cool nod to Tactics. Too bad they didn't leave her covered up with leggings like Agrias, because that was an awesome trend, and instead decided to shred her outfit into multiple layers of teeny slices of cloth that somehow form to make a dress. :(
