"Oh no! My very revealing and highly ineffective armor is no match against the lewdness of these pervert foes!" "Then why don't you wear something more practical?"
"Silence fool! A lowly peasant without honor like you would never understand!"
@nightwatch25 - It's not like a honorable noble-sama can just admit she wears this very revealing armor because she wants lewd things to happen to her.
@Tearsax - I imagine if a girl wears sexy revealing clothes all the time, she'll either grow up to consider men perverts who stare at her all time, or will assume it's natural for her to draw attention for some unrelated reason (the way that classical magician from Yoku Wakaru Gendai Mahou does it).
