Sexy girl group Stellar has some more demure 'Sting' teaser images for you. Yesterday, we saw Hyoeun and Minhee's teaser images, and now it's Gayoung's turn.

If the girls were a little too sexy in their last comeback, this concept takes both innocent/cute and sexy, and mixes it all together. Gayoung is provocative as she points her behind out, but still keeps it classy in cute outfits and minimal makeup.
