Most Helpful Guy
Typically when a guy likes a girl, he will go out of his way to impress her in every way he can. Bathing, dressing up, smelling good, acting "masculine" or funny, etc. But this isn't always the case. I have a friend whose idea of "dressing up" seems to be much less formal than most other people. So in his case it wouldn't seem like he's making an effort in that dept. But it's just the way he dresses. There is no simple answer here. But typically, like I mentioned earlier, I guy will go out of his way to impress the girl he likes.
