Keira Knightley flaunts extremely tiny waist in new dress

Actress Keira Knightley surprised everyone by flaunting an extremely tiny waist at this year's Paris Fashion Week.

Knightley, who is popular for her skinny frame, sported a black-and-white optical illusion dress at the Chanel show that happened earlier today, reported E! Online.

The outfit featured a full skirt with a super-tight-fitting cinched waist under a very structured crop top. The dress also sported a black bow at the neck.

She paired her high-fashion look with gold heels and a black Chanel bag.

After posing for pictures outside the Chanel show, Knightley and her rocker husband James Righton, sat together on the front row at the show.
