Modesty kink 

A form of kink where one fetishizes a person who acts or dresses modestly in public. By form of knowing or dreaming about the persons kinks behind closed doors or what they would do. The charm is in not being able to see the persons sexy features and instead thinking of it.

I have a modesty kink.

Someone using their own sexually loaded morality code to obsess about defining and setting rule standards on how other people should dress.

Prudish authoritarians are the most sex-obsessed people on earth. That goes for modesty kinksters and homophobes alike.
