Yesterday, we reported the male baby-faced beasts of Korea, and today Nate is taking a look at girls who have perfect eye smiles. If you haven't heard of this term before, it's the crescent shape that an eye curves into when a person smiles. In Korea, guys tend to love girls who smile this way. So which girls have the best eye smiles? 1. SNSD's Tiffany When SNSD first debuted, Tiffany was immediately loved by many as she became known as 'that girl with the eye smile' on variety programs. Her smile was so well known that when she was asked to show off a talent on a show, she would just smile and the guys would melt. 2. KARA's Seungyeon Even though Seungyeon recently confessed that she believed her non-smiling face is not so great, her smiling face more than makes up for it! Though she's one of the oldest members of KARA, she looks pretty young with to her cuteness. 3. f(x)'s Sulli Every time Sulli moves, people go crazy. She is one of those rare girls that guys and girls love. Her pale white skin goes perfectly with her plump lips when she smiles. She's nothing more than lovable and she never forgets to smile wherever she goes. From what I've seen of her, she seems like she smiles 24/7. So what makes eye smiles so lovable? Well, Koreans attribute the look to "aegyo fat," which is the area of skin underneath the eyes. One plastic surgeon said that this "aegyo fat" makes people look cuter and gives the illusion that they have bigger eyes. Who do you think has the best eye smile?
