Kate Middleton Steps Out In Sparkly Royal Jewelry Goodness.

Kate Middleton attended a glamorous charity gala at the National Portrait Gallery in London last night, as a royal patron of the gallery should.

The night's dress code: "black tie with a hint of sparkle," The Daily Mail says, and KMid brought enough sparkle to compensate for people who forgot to read their invitations properly. (There's always someone.)
