If you got it, flaunt it!

That's Jennifer Hudson's latest motto: The Oscar-winning actress showed off her transformed size-4 body in a breathtaking Michael Kors navy gown with a nude panel from the Fall 2011 collection. The 29-year-old was on hand to celebrate the iconic American designer and his 30 years in the fashion biz on March 7 during Paris Fashion Week.

We adore that the Weight Watchers spokeswoman went for simple and sophisticated -- we were a tad disappointed by the red-hot Atelier Versace gown she wore at the 2011 Oscars.

Flawless makeup like glam glossy lips and winged liner were the perfect touches. And the "Dream Girls" star sported some new caramel highlights too.

Hudson and her svelte figure rubbed elbows with some fashionable folk, including Vogue's Anna Wintour, Carine Roitfeld and her Vogue Paris successor, Emmanuelle Alt, Claudia Schiffer and Mary J. Blige.
