First Lady Mrs. O and Samantha Cameron started their Wednesday by serving U.S. and U.K. military families at a barbecue held at 10 Downing Street. For the event, Mrs. O chose a black and white print dress featuring a sheer top and beaded belt by House of Lavande. Fancy! 

Update: Thanks to various readers who have spotted Mrs. O's dress! The First Lady wears Tracy Reese Pre-Fall 2011, seen here. For jewelry, Mrs. O wears an armload of moonstone, jasper, colored diamond and white coral bracelets all by Jordan Alexander and available at Fragments.

Well, if reuniting First Lady Mrs. O and the Queen weren't exciting enough, let's throw Kate Middleton (make that Catherine, Duchess of Cambridge) into the mix! Oh my goodness!

For this historic occasion, Mrs. O has chosen a delightful dress. The mint hued floral frock is the gorgeous work of Barbara Tfank, from the designer's Resort 2011 collection, seen here. A pink cropped swing jacket also by Barbara Tfank and jeweled brooch complete the look.

A note on Catherine: Grazia UK reports that the Duchess wears the Shola Bandage Dress from high street retailer Reiss. More on the dress, here.

Update: On the jewelry front, Mrs. O wore Phillips Frankel amazonite and ruby earrings available at Fragments in New York. The pin is a 1940s Hobe brooch from House of Lavande.
