On today's KBS2TV's KPOP World festival, girl group T-ara and Sista showed off not only their dance moves and songs, but also their sense of fashion. As shown in the stills from the show (see above), Sista opened the show with their powerful performance of "So Cool" in shimmery silver miniskirts. Each girl's outfit was a slightly different version of the silver outfit as some were off-shoulder or one shoulder. The girls looked confident on stage, and their outfits garnered a lot of praise.

T-ara was also dressed to impress that night. Each of the group members appeared on stage in a gold jumpsuit with plum-colored jackets on top. Halfway through their performance of "Cry Cry," the girls took off their jackets to reveal a translucent top, and scarves, which would serve as props during their song.
