Sexy hot quartet SISTAR dressed up in elegant dresses for their latest CF for online shopping hub 11 St.

As the representative models for 11 St. the sexy girl group looked refined, classy, and incredibly sophisticated in classic evening gowns. Their looks are strikingly different from their typical girl group look which consisted of shorts, cropped tops, oversized shirts, and others. For their shoot, the girls of SISTAR toned down their usual sexy and fierce personality for a more classic look.

Soyu and Bora show off their long, slender bods as they wear long evening gowns while Dasom and Hyorin flaunt their enviable toned legs as they wear sexy cocktail dresses.

According to a representative of 11 St. the advertisement was filmed with the theme "whisper". "You will want to tilt your head as you want to hear SISTAR's whispered messages," the representative said.
