Girl group Girl's Day's agency stated their side regarding the issue with swimsuits.

"The swimsuit outfit in the teaser of their new song 'RING MY BELL' music video is only a concept to portray a cool image for the hot summer. They will not be actually wearing swimsuits on stage," said a representative of Girl's Day's agency Dream T Entertainment.

Girl's Day had recently released the teaser for their "RING MY BELL" music video.
