This week on the red carpet, the ladies of Tinseltown were all about looking pretty and polished. No one does that better than British beauty Naomie Harris. The James Bond beauty dazzled us in a beautifully embroidered Zuhair Murad sheer gown while attending the 'Diamonds Are Forever Gala. Looking especially royal in a fitted blue Roland Mouret design, Catherine,the Duchess of Cambridge showed off her lithe physique at SportsAid’s 40th Anniversary Dinner. Even Katy Perry received the demure memo. The 'Roar" songtress, looked like the picture of a lady in Oscar de la Renta while attending the Cindy Sherman: Imitation of Life” Exhibition at the Broad Museum in L.A. Spicing things up in Nashville, Carrie Underwood graced the CMT Music Awards red carpet in a pretty pastel, watercolor gown by Mikael D. While the shades are soft and sweet, Carrie added a touch of sex appeal via vertical bodice cut-outs, and a thigh-high slit. On a flirtier note, model Karlie Kloss brought layers of feminine fun to the CFDA Fashion Awards. Donning a white cut-out bow dress with Swarovski crystals, Karlie looked like the belle of the ball.
