I don't care about fashion, expensive clothes, or wearing different things everyday. BUT, I like to see both women and men dress up nicely. Meaning, wearing nice colors that go with each other, having some sort of a style, looking neat and hygienic. You get the picture.
I spend more money on my clothes than your average guy. I have style and I am almost always well-dressed. It is not the most important thing, but it appeals to me very much.
she can dress the way she wants as long as she is comfortable
I put a lot of thought into how i dress myself. I'm a pretty reserved, shy dude so it's sort of how i communicate what kind of person i am. The average person would probably just write me off as a hipster, but that's fine with me. The kind of friends/girls i want to attract, think how i dress is cool.
So in a nutshell, how a girl dresses is pretty important to me, because it says a lot about who she is. If she dresses plainly or badly, i can assume she's probably not my type. I guess i'm sort of shallow, in a way.
