Concept photos of SNSD's "Black Soshi" concept have been revealed throughout the past week. First came Yuri, then Taeyeon and Seohyun, Hyoyeon and Sooyoung, Jessica and Sunny, then lastly Yoona and Tiffany. The pictures were just a way to tease us for the new song Run Devil Run. The order of the picture release initally seemed meaningless to me, but it turns out there was a reason why Yoona and Tiffany's photos were  released last. SNSD's visual director team stated that Yoona had the most drastic change for Black Soshi. She was the one to take the big step and do something completely new to her hair, and get thick front bangs. She's never had bangs since she's debuted so this is very new. I'm not really loving the bangs on Yoona but I'm sure many fans do, since it makes her face look even smaller than it already is. The team continued to talk about Tiffany's hair. They said that in Oh!, Tiffany's hair had an innocent and fresh feel to it, but this style is more mature. Funny how the same cut can work both ways in terms of concepts. SNSD's MV is set to come out tomorrow, and their comeback performance will be held this week on Music Bank!
