Anything as long as its clean. Shoes used to be the first thing I would like at when I checked out at guy. Now not so much.
I am a girl and I usually just like guys to have their own style. You can usually tell when someone is wearing a different style that doesn't suit them, because they can't carry that look and I have always found it rather awkward.
I am still quite young but I cannot get over the whole musician style.
