Dress down just a tad. I know it sounds weird but I sometimes feel intimidated when a girl is dressed up. I feel like I need to impress her more or something. however when she's more casual with her dress then I feel more at ease.
The only reason why I wouldn't say "dressed up" is because I've always heard that women who do that, expect men to be the same way. I'm not one to believe in being "dressed up" all the time, because I find it to be "metro" which is just a really straight way of saying "in the closet". I'm straight but I do know that women like a well dressed man (I just believe it shouldn't have to be all the time).
I guess what I'm saying is, as long as you don't care what I wear, then I don't really care what you wear
