A signature style is a specific look that a celebrity has perfected. We’ve seen oh-so many amazing style choices in 2011, but now we’re going to zero in on some of our favorites. Take a peek and tell us which looks you absolutely love!

What is Niall’s signature style? Well, he just can’t get enough of zip-up hoodies and polo shirts.

Niall always looks completely comfy AND cute while wearing his hoodies, and he make a short-sleeved collared polo shirt look super hot. Both are simple and casual looks, but Niall looks amazing in both!

Is there another signature style he has that we missed this year? Tell us in the comments and on Twitter!
