4. Jessica Simpson 2005
Also attending the 2005 show was Jessica Simpson, who made us do a double take with her barely-there ensemble. From the back, it looked like she was wearing only lingerie. But her outfit actually consisted of black short shorts and a white ruffle cami with a cold-shoulder design and a draped back, exposing her lace bra.

The singer styled her look with a pair of black T-strap peep-toes. To finish off, she wore her blonde hair in a voluminous curly style.
