Fashion designer Diane Von Furstenberg says she is "embarrassed" after criticizing Michelle Obama for wearing Alexander McQueen to a State Dinner, rather than a dress by an American label."I said that Mrs Obama has been extremely supportive of American designers, but clearly we were disappointed that she chose to wear a British designer for the state dinner," she told Tina Brown at a Daily Beast-sponsored breakfast last week. "From there, I was so embarrassed that I am definitely going to write to her. She has been super-supportive to American designers." Asked why Obama might have chosen a dress by a foreign designer, Von Furstenberg replied: “I don’t know. Maybe she liked the color! I’m sure she had options like all of us. Or she asked [President Obama], "Which one do you like?"'
