Michelle Obama Style: Polyvore Showcases First Lady's Style From 2008 Election To Now

It's been four years since U.S. First Lady Michelle Obama strutted onto our style stage: dazzling us in Thakoon (as her husband, President Barack Obama, accepted the Democratic nomination in 2008), donning Canadian designer Jason Wu and recently wearing Thom Browne (at the third and final 2012 presidential debate).

Her sartorial smarts have wowed us at every turn, including her ability to mix high-brow fashion with lower-priced separates (she's as big a fan of J.Crew as we are).

In honour of the 2012 U.S. presidential election, Polyvore has rounded up some of the First Lady's most beloved outfits.

Check out the timeline of Michelle Obama's top style moments from the 2008 election to now.
