Glamour spell is a context that exist within FFXIV lore. Even Alisaie made a joke about it during Stormblood.
FFXIV tells your story, and you are the main character of your game, so, if I see a Roe using a dress/bikini/whatever, I just see another adventure using glamour in the way he wants, my character sees a funny guy/girl or someone with poor fashion taste, she laughs(or not) and moves on. It just don't interfere with my ingame life and don't break my immersion.
