A Crown Jewel

After a meet and greet with the royal family, the President and First lady met with Britain's Prime Minister David Cameron and his chic wife Samantha Cameron at 10 Downing Street. The Obamas also received a special tour of Westminster Abbey. Quite a day! 

For these events, Mrs. O changes ensembles, wearing a delightful mix of jewel tones on this occasion. The First Lady wore a punchy purple dress featuring a draped neckline and black chiffon trim. The dress was paired with a vibrant blue coat and jeweled belt at the waist. Navy black pumps completed the look. 

Per Red Carpet Fashion Awards, Mrs. O wears a dress by Roksanda Ilincic from the designer's Pre-Fall 2011 collection. Ms. Ilincic is a Serbian-born, London-based designer with a growing presence in Mrs. O's closet! The First Lady last wore Roksanda Ilincic for a White House reception to welcome President Hu of China in early 2011. Mrs. O's blue double wool crepe coat has proven to be the fine work of Narciso Rodriguez. 

For those interested in Samantha Cameron's choice, the Prime Minister's wife wears a Spring 2011 dress by Peter Pilotto, also a Mrs. O favorite!

The first lady kicked off a West Coast tour today, speaking in Bellevue, Washington at a fundraising luncheon to support Senator Patty Murray. For the appearance, Mrs. O wore a printed blouse by Peter Pilotto, from the designer's Fall 2009 collection. 

It is a full week for the first lady. Tomorrow Mrs. O is scheduled to speak at The Women's Conference, hosted by Maria Shriver, and on Thursday, will appear on the Ellen Show. Stay tuned!

Purple has certainly become Mrs. O's color of the season. Above Mrs. O is pictured as the first couple honored retiring White House butler James Ramsey on January 25th. Mrs. O wore a purple velvet cut-out jacket by Azzedine Alaia, which coordinates with the dress worn for Oprah's White House Holiday Special in December, below. For last week's event, Mrs. O paired the jacket with slouchy purple trousers and a printed blouse by Peter Pilotto (thank you, chrystelle, for identifying the latter).

First Lady Mrs. O and and Dr. Jill Biden have been in the Bronx this afternoon, visiting the James J. Peters VA Medical Center. They're expected to attend Game 1 of the 2009 World Series this evening, which will be dedicated to military heros.

Mrs. O is wearing a patterned blouse in autumnal hues, paired with black pants, while Dr. B is dressed in All-American classics. We imagine they'll change for the game?

Update: Ari, you're our hero today! Ari has confirmed that Mrs. O wears a blouse by Peter Pilotto, from the desingner's Fall 2009 collection, seen here.
