Michelle Obama & G-20's Other First Ladies: Who Was Best-Dressed? (PHOTOS, POLL)

The last time we saw First Lady Michelle Obama at a G-20 Summit was when she and the president hosted one in Pittsburgh last September.

Now the G-20 leaders and some of their spouses (Carla Bruni stayed home this time) convened in Toronto this weekend, where they were hosted by Canadian Prime Minister Stephen Harper and his wife Laureen. On Saturday night the Harpers welcomed the leaders for a working dinner; the spouses dined separately.

According to the pool report, "the First Lady's office is pleased to let you know that Mrs. Obama is wearing tonight an '[Azzedine] Alaia dress, and vintage costume jewelry from a company in Toronto called n&n vintage.' and 'The jewelry is costume, not real,' says FLOTUS' office."
