Girl group SISTAR are gearing up for their comeback, and this time, they'll be transforming into lovely "afternoon party girls"! This glamorous concept for their third mini-album was epitomized in the members' wardrobe. Sequinned mini-dresses and shiny high heels emphasize the image of girls looking to have fun; member Soyu in particular drew netizens' attention with her sleeker figure, the result of an 8 kg weight loss. SISTAR's agency, Starship Entertainment, commented on August 4th, "In preparation for SISTAR's comeback, these past nine months have been spent perfecting SISTAR's music, look, choreography, and performance. Please look forward to it." This album's title song, "So Cool", has been described to be an energetic dance track. SISTAR will be making their comeback later on this month, so stay tuned to allkpop for updates! Source + Image: OSEN
