Michelle Obama attended the gala to celebrate the Time Magazine’s 100 Most Influential People. She looked stunning in a black Azzedine Alaia sleeveless gown.

Underneath she wore a Peter Soronen corset and she set the look off with several strands of necklaces, a sleek hairstyle, and diamond stud earrings.

In her speech, Michelle stressed how important public service is:

“Careers focused on lifting up our communities, whether it’s helping transform public schools or training workers for green jobs or helping low-income families access healthcare, these jobs are not always obvious,” she said. “But at a time when our nation is facing unprecedented challenges, encouraging careers in public service and social innovation is more important now than ever.”
