Photographer Paolo Roversi opened up to Italian newspaper Corriere Della Sera about working with the Duchess of Cambridge for the portraits, which were taken in November at London's Kew Gardens. He even shared that Prince William and the couple's three children — Prince George, 8, Princess Charlotte, 6, and Prince Louis, 3 — helped pick one of the photos that would be shared with the world.

The black-and-white image where she sits in a traditional side profile pose seen in many royal portraits over the years "is regal and has a maturity that goes beyond her age, and the white dress dampens the seriousness of an effigy." Meanwhile, the photo of Kate in a red one-shoulder gown in color is "a little more glamorous." Roversi said he wanted to keep the portraits "contemporary" by using "only natural light, little makeup and no hairstyle." Kate Middleton on her 40th birthday.

The portraits will enter the permanent collection of the National Portrait Gallery, of which Kate is Patron. Ahead of the Portrait Gallery's re-opening in 2023, the photographs will be part of its Coming Home project, a nationwide initiative that sees portraits of well-known individuals being sent to locations that they are closely associated with.
