Keira arrived wearing a ladylike Nina Ricci design, which featured a daring lace-front bodice.
A Chanel handbag, black tights and velvet Roger Vivier sandals completed the relatively low-key ensemble.
See all the stars at the 2012 National Board of Review Awards here:
- George Clooney and Stacy Keibler<p> George and Stacy were playing resident golden couple at the 2012 NBR Awards, with him dapper in tux and bow tie, and her elegant in floor-length Marchesa. George took home the best actor award for his role in <em>The Descendants</em>.</p>
- Keira Knightley in Nina Ricci<p> Keira Knightley went racy in lace Nina Ricci for the evening, teamed with Roger Vivier sandals.</p>
- Helen Mirren<p> The epitome of glam, the ageless Helen Mirren swept down the red carpet in this black floral detail gown.</p>
- Rooney Mara<p> Rooney Mara stuck to her now signature style of a Little Black Dress, though this time she looked to Miu Miu for the honour.</p>
- Carey Mulligan<p> Carey Mulligan might have skipped the red carpet, but managed to snap her arriving outside. Would have been a crime to miss that rose-beige Lanvin.</p>
- Felicity Jones<p> Brit actress Felicity Jones continued the evening's trend for LBDs in her go-to red carpet designer, Dolce & Gabbana. (Well, she is the face of the brand.)</p>
- Tilda Swinton<p> Tilda Swinton bucked the trend for dresses, opting for high-waisted trousers and a silk blouse. Tilda took home the best actress prize for her role in <em>We Need To Talk About Kevin</em>.</p>
- Jessica Chastain<p> Jessica Chastain embraced winter florals in her curve-boosting Zac Posen dress.</p>
- Chloe Moretz<p> Chloe Moretz brought a splash of colour to the evening's proceedings, in scarlet Miu Miu.</p>
- Naomi Watts<p> Ever elegant, Naomi Watts opted for classic black and gold Stella McCartney.</p>
- Emma Stone, Jessica Chastain and Ahna O'Reilly<p> <em>The Help</em> ladies took home the award for best ensemble cast during the evening.</p>
- Keira Knightley, Michael Fassbender and Carey Mulligan<p> Keira Knightley and Carey Mulligan were joined by actor Michael Fassbender for the event.</p>
- Viola Davis<p> Viola Davis flaunted her curves in a fitted Lauren by Ralph Lauren dress.</p>
- Octavia Spencer<p> Another of <em>The Help</em>'s stellar cast, Octavia Spencer kept her styling simple in draping black David Meister.</p>
- Ahna O'Reilly<p> Relative newcomer to the red carpet scene, Ahna O'Reilly shone in metallic stripes.</p>
- Emma Stone in J. Mendel<p> Emma Stone complimented her porcelain skin with a cream J. Mendel dress - while the red lip and golden heels prevented her looking too washed out.</p>
