On MBC "Music Core" that aired on July 21, SISTAR Soyu performed on stage with their song, "Loving U."

On the show, SISTAR all wore white jump suits and showed off their cute charms. However, Soyu couldn't dance properly and
had to resist from dancing big because of her revealing outfit.

Other members wore white shirts under their jumpsuit, but Soyu wore a comparatively loose jumpsuit that showed a lot of her body.

When Soyu had to bend over to perform a dance move, she had to cover her cleavage up and she continued to dance small compared to other members.

Internet users commented, "How can you dance when you are supposed to wear that kind of a stage outfit?", "She looked so uncomfortable throughout the whole performance" and "Her stylist should have paid more attention."

On the other hand, Soyu once said on a previous show program that she hated wearing revealing outfits on stage.
