This week was all about...magic and magenta. And the winners are...

Sarah Jessica Parker working it in a strapless L'Wren Scott mini at the “Did You Hear About The Morgans?” premiere in London. While SJP rarely disappoints on the red carpet (with the exception of the "acorn" incident), this was one of her "Carrie Bradshaw" moments. From her voluminous waves to her purple Charlotte Olympia heels, not a thing was out of place.

Zoe Saldana shining in a silver RM by Roland Mouret fishtail gown at the “Avatar” World Premiere. Zoe is one of my favorite women to watch on the red carpet, and this is the perfect example of why. Heavily sculpted shoulders add a fresh, almost edgy, touch to this otherwise Old Hollywood glam gown. This is my favorite of the group.

Selena Gomez in a strapless Notte by Marchesa gown at the UNICEF Snowflake Ball. This simple sensation is right in tune with Selena's innocent style. While I would've liked to see some beading along the bodice or waist, the cascading bow adds an adorable touch.

Victoria Beckham wearing, you guessed it, Victoria Beckham at the 2009 British Fashion Awards. I love the shoulder embellishments and the way the bodice is gathered right below the bust line. Classy.

Kerry Washington in an off-the-shoulder Marchesa number at the Broadway Opening Night for “Race.” While the beading and neckline of this dress are rather demure, the bright, magenta color and pleating along the skirt keep things fun and upbeat.
