Maybe other people don't find them shitty? And the new character models (in game) are MUCH better than before.
If you're concerned about her dress, maybe you should know that in Xenoblade you see the armor you equipped on your character, in X they even introduced an option to equip two different sets, one for stats and one for aesthetics. You can dress her like a nun if you want.
