The first time I saw these girls, i thought they looked like dolls. At the beginning, my eyes “squinted” because at glance they look all the same. It was difficult for me to distinguish them and I think there were too many members. But now I can recognize each of them, they are: Taeyeon (leader), Jessica, Yuri, Hyoyeon, Tiffany, Sooyoung, Seohyun, Yoona, and Sunny.

This girl band officially released their debut in 2007, under SM Entertainment with single “Into The New World”. Until now these girls have gained a lot of success not only through their songs, but also through their acting and modeling.
They managed to create the sexy and sweet image and it is presented on their clips. I like their appearance in the “Oh” clip and “Run Devil Run” clip..they look cool!!!
