Michelle Obama decided to take a walk on the wild side while hosting the White House Dance Series in Washington, D.C., on Sept. 7.

Wearing her go-to thick Alaia belt and a white cinched-waist Byron Lars dress with black floral-shaped polka dots on the lower half and a sheer black sleeveless overlay on top creating a leopard pattern, the first lady welcomed guests to the event.

It was the White House's first celebration of American dance -- from ballet to hip-hop -- as well as a tribute to dancer/choreographer Judith Jamison.

The mashup of a dress (which shares some characteristics with this vibrant tunic by Duro Olowu) is not the first time Obama has donned a frock by Lars, an American-born designer who, according to his website, specializes in "twisted American classics."

On June 4, she wore his pale peach '50s-style dress to the White House's tribute to Paul McCartney.
