I don't mean slutty or all the time. Just like if your girlfriend wants to go out with her girl friends and she wears a dress that shows a little leg and cleavage. Do you find that disrespectful? My boyfriend always gets on me about this.
If I truly trust her that she will not try to attract other guys or anything that I might not like, then I am perfectly fine with it. If she is with me and she dresses sexy, oh baby, I would love it because everyone will look at how hot she looks and that she is with ME! This is good for both of us.
