On the 28th, the ladies of SNSD looked classy and chic performing "The Boys" on KBS Music Bank dressed in trendy and modern equestrian uniforms. They lived up to their title as the idol queens of K-pop, belting out the song live without a hitch and never missing a dance beat. But the one thing that most caught the viewer's attention was maknae Seohyun's outfit. The singer who has a quiet and timid image off-stage exposed her midriff, putting on what might have been her sexiest performance yet. SNSD competed against Huh Gak for the #1 spot this week, and was able to take home the K-Chart win. Source & Image : OSEN via Nate
