It's been 50 years of scantily clad supermodels!
The buxom blonde flaunted her claim to fame in a skintight Antonio Berardi gown with zipper detail that barely kept her cleavage bridled.
The look was styled perfectly with David Yurman and Dior jewels, a flouncy 'do, and fresh makeup.
Seems like Kate's style is getting chicer and chicer!
