Keira Knightley's Colourful Week On The Red Carpet: She Wears Mint Erdem Gown To The LA Premiere Of Anna Karenina

In movie-promo terms, this week is ALL about Twilight. Kristen Stewart is the undisputed queen of the red carpet, causing much fash-debate over her barely there Zuhair Murad creations she wore to the London premiere and the LA premiere. R-Patz and K-Stew are ALREADY in Madrid, a cool 12 hours later than their last premier, so clearly no-one can compete this week with their Twilight sprint.

But Keira Knightley is winning the long-distance fash-off as she is stillll promoting Anna Karenina in a number of fabulous spring summer 2013 gowns. Last night was the LA film premiere and Keira wowed in a custom Erdem strapless mint gown, inspired by his S/S 2013 collection. Keira opted for simple jewellery with her Erdem gown, wearing a pair of white diamond Chanel earrings. We also love her oh-so pretty twisted updo and pink lip.Keira is the first to wear Erdem S/S 13 on the red carpet, which we could have predicted at Grazia HQ as Erdem told us that she is his favourite starlet to dress, as he said: "I love Keira! She is always... she's such a... she's SO beautiful! So I'd say her." Keira clearly loves Erdem too, as she wore a purple floral dress to the premiere of The Edge of Love and a floor sweeping Erdem gown to the Laurence Olivier Awards.Keira didn't stop at just one stunning frock last night, as for the after party at the Greystone Manor Supper Club Keira slipped into an orange lace dress with cut-out sides with strappy nude heels.

Anyone else love seeing Keira step outside of her comfort zone and wear pretty pretty pastels? Green could well be Keira's new fave hue, as she wore a Burberry Prorsum green lace dress to appear on the Tonight Show with Jay Leno.
