First Ladies Night! See What The G-20 Wives Wore To Downing Street Dinner (PHOTOS, VIDEO)

*Scroll down for slideshow and video*

On Wednesday night Prime Minister Gordon Brown hosted a working dinner for G-20 leaders at 10 Downing Street. The delegates dined on baked Scottish salmon, Welsh lamb, and something called lovage (see the full menu here), all prepared by Naked Chef Jamie Oliver.

Other than the working and the dining, the most important issue of the evening was, obviously, what were the first wives wearing?

Michelle Obama--always the pragmatist--simply removed the black cardigan she wore to meet Queen Elizabeth earlier in the day, and voila! Dinner attire.

And where were the male spouses, Nestor Kirchner (husband of Cristina Fernandez de Kirchner, Argentina's president) and Joachim Sauer (husband of German Chancellor Angela Merkel) in the group photo?

Or see all of Michelle Obama's London outfits here.

The Obamas arrived early, to screams from the crowd that had gathered.
