Shake what your mama gave ya! Sistar are serving legs for days in a new dance practice video of their number 1 single, "Shake It."
Hyorin, Bora, Soyou and Dasom look stunning in the clip -- which was filmed at agency Starship Entertainment's HQ in Seoul -- as they wiggle their hips and strut their stuff to the catchy track.
Impressively, the girls manage to execute every choreographed move flawlessly in sky-high six-inch heels.
The group looks as sexy as ever in cropped tank tops and daisy duke denim cut-offs, which perfectly showcase their long and lean legs.
And it's clear they're giving it their all -- check out the sound of the members catching their breath at the end of the video.
