I own no v-necks. I just.. can't really imagine myself wearing them tbh. I'm more a casual, plain shirt & hoody kinda guy. It makes me look like a little ewok :3
I have two. One of them has the 'V' part too small. D: Then there's that one, where the shirt is small, but not the 'V' part. :\ There's one I saw that I love on the Hot Topic website. :D
