The 35-year-old's gown, which featured sheer long sleeves and neckline as well as a form-fitting bodice, made its return to the spotlight. Prince William's wife first wore this to Queen Elizabeth's 90th birthday celebration in April 2016. For Tuesday's event, she styled the look with 18-carat yellow gold drop earrings by Kiki McDonough and a Wilbur and Gussie gold glitter clutch. Kate's brunette locks were down in bouncy curls and her makeup accentuated the color of the dress.

Kate has been Patron of the National Portrait Gallery since 2012 and previously attended the gallery's gala in 2014, where she looked stylish as ever in a Jenny Packham evening gown and a diamond necklace borrowed from the Queen. The Duchess has since seen her own portrait grace the walls at the gallery, after her shoot for Vogue's centenary celebrations was displayed as part of the Vogue 100: A Century of Style exhibition.
