Keira Knightley Shows Off Insanely Small Waist in Surprising Chanel Dress

Actress hits Paris Fashion Week in a shocking dress

Way to make a bold fashion statement, Keira Knightley!

The 28-year-old actress hit the Chanel show at Paris Fashion Week Fall 2014 earlier today in a very unique and surprising Chanel look.

The Anna Karenina star showed off her insanely small waist in a black-and-white optical illusion dress that featured a full skirt with a super-tight-fitting cinched waist under a very structured crop top. The look was accented with a black bow at the neck. She completed her high-fashion look with gold heels and a black Chanel bag.

While we're not sure if the dress is one piece or made up of separates, the tight middle definitely accentuates her super fit and thin frame.

After posing for pics outside the Chanel show, Knightley and her rocker hubby, James Righton, sat together front row and watched the models stomp down the catwalk. Righton looked handsome in a blue and white suit. The lovebirds cuddled in their seats and posed for pic together.

Meanwhile, today's Chanel show featured a very unique runway setting. Designer Karl Lagerfeld commissioned a grocery store setup for the show, which featured A-list models like Cara Delevingne and Kendall Jenner. Rihanna also took part in the big, supermarket-themed show.
