That argument makes no sense. Real life does not correlate with the game on 1 to 1 basis. You don't see people walking in their underwear/swimsuits in a city in real life. So if you have the courage to walk in the middle of city with your underwear/swimsuit on you deserve to ask for the people to not ask for this feature.
Why does everyone ignore the point that it's entirely optional? If I turn off battle animations the game looks bad. It's worse than a mismatched outfit, but noone has a problem with the feature existing? Why does having the option to turn off glamour rile people so much?
