Ahead of their U.S. album slated for mid-May, Wonder Girls have taken a handful of sponsor photos for popular Korean clothing brand Pacumong midst their busy schedule. Wonder Girls modeled various Pacumong tops in their practice room at JYP Entertainment, exuding a casual side of them while still retaining their natural beauty. Even new member Lim was praised for her presentable appearance, as seen in her individual picture. Somehow smuggling her way into most of the photos, dorky member Yubin displayed her penchant for the camera. The camera must love her right back because she looks beautiful in these shots. Can you find Waldo Yubin in the pictures below? [gallery order="DESC"] Aside from their U.S. album, Wonder Girls will embark on an American tour in May. Their opening acts have already been chosen as 2AM and 2PM, the male counterparts of their JYP fambam. Although the wait for their return has been painfully long, let us remain patient for a little while longer as Wonder Girls' comeback is just around the corner.
