On October 24, T-ara's agency Core Contents Media revealed a picture of Hyomin dressed in retro fashion with sunglasses, cap, striped T-shirt, and most notably, baggy overalls. She is striking a casual model's pose while holding an LP record.

The agency revealed that they are currently mulling over whether this picture would reflect the concept for T-ara's upcoming new track "What Should I Do," which they previously said would be another retro song.

Interestingly, the music score and lyrics of composers Shinsadong Tiger and Polar Bear's "What Should I Do" appear to be in the above picture.

T-ara is currently promoting "Number 9," but is already preparing to make a retro-themed comeback with "What Should I Do" on December 2.
