The actress-and-model opted for the head-turning outfit as she attended the front row of Mark Fast's Spring/Summer 13 collection. Kelly took to Twitter ahead of the runway presentation to gush about the dress - which is from her very own New Look collection.
"On my way to Mark Fast Show wearing one of my own dresses! X (sic)," she wrote.
Kelly opted to team the low-cut dress with a pair of skyscraper black patent heels, and accessorized with a metallic gold snakeskin bag. The beauty wore her brunette locks down and kept her make-up look natural - adding a hint of vamp with red nails.
Kelly later showcased her enviable figure in a form-fitting nude dress at the Giles London Fashion Week show.
The 32-year-old star showed off her assets in the figure-hugging outfit, which clung to her curves and reached below her knee. Kelly gushed about the runway show on Twitter later on.
"Giles as always great show! Great catching up with mates after in the pub and pulling pints in Giles Couture! #LFW (sic)," she exclaimed.
The Burberry Prorsum show yesterday drew in a star-studded crowd.

No matter how stringently your loved ones warn you, that won't stop you pursuing a romantic interest. You're utterly captivated by someone who exudes warmth, charisma and drama. The two of you get along very well, but beware of the financial toll this relationship will take. The object of your affection likes expensive things. If you're not able to provide them with the luxuries they crave, there will be problems. Then again, you have the potential for being a good provider, so all may be well.More
