Girls’ Generation have been actively promoting their double title tracks “You Think” and “Lion Heart”. The group has been performing the two tracks on various weekly music programs, such as Music Bank. When the group was commuting to the KBS building for taping of this week’s episode, Yoona could be seen styling in all black from head to toe. The singer wore a sweater featuring sweet ruffle detail on the front from Sandro ($275). She also carried a Cross Print Clutch ($524) from Givenchy.
