Why do people find it awkward that I don't like girls who dress provocative?

So people find it is so awkward that I do not like girls who dress provocative. I mean I like girls who dress sexy but to a limit that is. My friend kara thinks its so awkward that I don't like the way she dresses when she goes out at night. She would wear mini dresses and wear high heels stiletto pumps. I mean I like girls who wear heels but they have to look classy in it. What I find is sexy is a girl who wears skinny jeans or flare jean pants with stiletto heel pumps and a cute top with her hair tied up in chopsticks. My vietnamese fiancee dresses like that and I love it. I'm more of a classy men I dress nicely in a button up shirt and slacks whenever I go out so that's why I prefer girls who dress classy. I prefer girls who dress classy and look sexy more than girls who dress provocative like Kara. Why do they think it is so weird that I don't like girls who dress provocative and prefer classy girls ?? Seriously I prefer classy girls because I like girls who dress like that and because I don't want no one eye balling my wife when I take her out to dinner or something.
