Now you didn't think we could talk about One Direction without mentioning their looks, did you? From Harry's curly hair to Zayn's tattoos, each boy has a little trademark unique to them and we love them for it! They each have their own personalities; there's the flirty one, the cute one, the funny one, the mysterious one and the sweet one. They're individuals - and yet they work so perfectly together. Just over two years ago, they didn't even know each other existed and now they're sat at the top of the charts as a band. That's pretty amazing, don't you think? Do you love One Direction?
