Michelle Obama is back at it as the first lady of fashion, wearing a bright yellow dress by Prabal Gurung and and a sleek updo at a White House state dinner hosted by President Obama for African leaders Tuesday night.
This isn't the first time Michelle has stunned in a Prabal Gurung piece for a public appearance — she's a loyal fan of the Nepalese designer, donning his designs for Arthur Ashe Kids' Day last August:

And a 9/11 memorial concert in Washington in 2011, among other events.
