I don't think these ladies from this ffxiv image look "un-sexy" but I'd personally love a more elegant appeal from the clothing. I think Final Fantasy Tactics had great art concept for female and male attire that wasn't too over the top, but had a little sex appeal for both genders.
And maybe even a bit more characterized like some of the main characters:
But I definitely like the beginning feel of the gear now. I know a lot of people are looking towards that black mage armor that Yoshida sort of spoiled, but to be honest, I think it looks a bit over the top. Don't get me wrong, I love black mages and characterization from gear, but I find it hard to imagine people running around in Eorzea wearing that set. It feels a bit...false and unfitting for the world we know it as now. We've never seen any other characters in this game wearing such outlandish gear. Even the Garleans look relatively believable.
