Cheeky! Nicky Hilton showed off a surprising amount of skin (even for a Hilton!) during Paris Fashion Week on Sunday, July 5.

The younger sister of Paris Hilton wore a white cutout dress to the Versace haute couture show that left little to the imagination. The mod look featured two sheer cutout panels, the bottom of which clearly showed her underbutt. (Who knew that was a thing?)

The dress also had several large cutout circles lined with metal hoops that put Hilton, 31, at constant risk of a wardrobe malfunction. Pairing the racy ensemble with white heels and a matching clutch, the heiress let her booty do the talking, posing for several over-the-shoulder pics.

Models Karlie Kloss, Doutzen Kroes, and Kendall Jenner walked in the runway show, which was also attended by Rosie Huntington-Whiteley and Naomi Campbell.
