Knightley wore a white and black Chanel that featured a super-fitted midsection between the two panels of the dress. The unique structure of the garment only served to accentuate her small waist.
Knightley's appearance at the fashion show is not the first time her figure has made headlines. Many have expressed concern over her thin frame for years, and the actress has repeatedly had to address anorexia rumors.
Knightley's choice of dress seems to show that the actress continues to accept her body just the way it is. The actress will star alongside Benedict Cumberbatch in The Imitation Game, set for release this year.
