I've always had a wide smile. In fact, growing up I was often referred to as The Joker. I felt self-conscious about it, but during my preteen years, I began to take notice of wide, toothy smiles on models like Niki Taylor. I realized that this feature was not just the most prominent, it was also the most beautiful. If I had to choose, I'd say that my mouth is my most distinguishing feature. What's yours?
