Third Time’s a Temperley Charm For Kate Middleton

Tonight, the Duke and Duchess of Cambridge attended the screening of Sir David Attenborough’s Natural History Museum Alive 3D in London.

We first saw this lace Temperley London gown on Catherine at the January 2012 premiere of War Horse.  She wore it again to a St. Andrews Dinner in November of that year, shortly before announcing her pregnancy.

The Duchess of Cambridge is Patron of the Natural History Museum.

Earlier today, Their Royal Highnesses visited South African House in Trafalgar Square to sign a book of condolence for Nelson Mandela.  The couple attended a screening of Mandela: Long Walk to Freedom the same day he passed away.
