That looks to be a prom dress, especially judging by the date of the photo. What looks so weird in that picture is the shadow of her little belly looks like a patch of hair, but is isn't. It's just a shadow. Would I let my daughter wear that to prom....f*** no!! It is too revealing and typical of a teeenage girl who thinks she's hot trying too hard to cause a stir. But she isn't showing the hooch.
That said, there is no justice that she didn't go home or even land in the bottom three. I am now left to question my faith in god.
