Style mens outfit help?

K my outfit. I would get on photobicket and take some pics but I can't right now. I'm on my iPod. So I got a church longsleeve white as the undershirt. I have a black/grey thin jacket (zip-up) with an inch sized collar. I have the jacket zipped up to about 3 inches from my collar bone. I have the church shirt collar popped up and I have the sleeves of the church shirt come up and overlap the jacket sleeve. I thought that it doesn't look good with 2collars but idk. That's why I'm asking you. I got jeans and some slipper shoes. If I could add a scarf that's be cool. Haven't tried yet. Please give some tips if I'm doing something wrong. Or something I should add on.
