Beyonce wowed in an elegant navy blue figure-hugging Victoria Beckham dress teamed with a super slick ponytail and a perfect pink pout. Giving a nod to her baby daughter Blue Ivy, Bey matched her dress with an electric blue mani-pedi.
And not to be outdone by her stylish sis, Solange looked ladylike and demure in a white billowing blouse teamed with a black and white print pencil skirt.
Hosted by Michelle Obama and Robert De Niro and wife Grace Hightower, the dinner was to raise funds for Barack Obama's re-election campaign.
