Keira Knightley shows off her slender frame in a little black lacy dress… but gets it oh so wrong with her clumpy and heavy heels

For someone with a delicate and tiny frame like Keira Knightley, a light, sheer black dress is the perfect outfit to flatter and define.

And the actress got it spot on last night at as she arrived at an event in New York in a very pretty black lace and heavy silk dress.

But unfortunately, it appeared that she hadn't thought too much about her footwear as she teamed the Nina Ricci dress with heavy black velvet heels, which she teamed with thick black tights that did nothing to flatter her long slender legs.

The actress, 26, was a guest at the National Board of Review Gala in Manhattan and after gracing the red carpet outside, she stopped for the cameras inside the event which was held at the held at Cipriani 42nd Street.

The lace panel dress looked lovely on her size six figure, which fell into a full heavy silk skirt, with the silk also adorning the sleeves.

But the thick strapped velvet shoes were
a poor choice and Keira should have opted for a thinner heel with
delicate straps and sheerer tights.

She was later snapped leaving the bash with her musician boyfriend James Righton, who plays keyboards and sings with the Klaxons.

Keira was at the event to support her new film A Dangerous Mind, in which she stars alongside Michael Fassbender, who was also at the bash.

Other British stars at the event included Carey Mulligan, who looked very cute in a light pink tasseled dress, and Dame Helen Mirren, who opted for a beautiful long black velvet dress, which had a sheer front which was dotted with velvet flowers.

And Tilda Swinton, who won the award for best actress for her role as Eva in the movie We Need To Talk About Kevin, based on the award-winning book, went with her usual androgynous look in a purple silk shirt and plum tailored trousers.
