The last night at National Portrait Gala, the Duchess is dazzling in another lace piece by one of her favourite labels, Temperley London.

The bespoke gown is thought to be based off of the 'Cleo' design and features long sheer sleeves with a belt and a beautiful floral lace overlay (which Kate seems to be quite a fan of).

It is also extremely reminiscent of her black lace Temperley 'Amoret' gown worn to a film premiere in 2012 . Both have the same silhouette with scallop detailing around the lower hips.

This gown has been worn once before, but we only got to see the top half of it in the car as William and Kate were driven to Windsor Castle to celebrate the Queen's 90th at a private dinner; I've been hoping that she would repeat it so that we could see it in all of its glory!

Kate debuted some new special edition earrings tonight from Kiki McDonough (I think these are like her 12th pair!). These are the 'Candy Pink Tourmaline and Green Amethyst DropEarrings' (£8,900/$11,000). They are described as "Stunning pear drop green amethysts and pretty round pink tourmalines surrounded by delicate diamonds set in 18ct yellow gold make these truly beautiful earrings."

Kate carried her Wilbur & Gussie 'Charlie Gold Glitter Clutch' which is available for £195/$240.

She also brought back her Jimmy Choo 'Dart' sandals from the back of her wardrobe. The elegant metallic leather shoe retailed for £660/$825 before selling out.

A stunning look for the Duchess last night, don't you think?

The Duchess of Cambridge attended the 2017 National Portrait Gala to help raise funds for the National Portrait Gallery's work in showcasing inspirational displays, offering learning opportunities and undertaking research.

Her host, Gillian Wearing, gave her a tour of the newest exhibits and special collections, explaining the significance of the works featured. Kate was shown exhibits including Howard Hodgkin: Absent Friends, and Gillian Wearing and Claude Cahun: Behind the mask, another mask.

She also saw the Mystery Portrait Postcard exhibition where invited artists, sitters and well-known individuals are asked to create and contribute with an A5 portrait. They are each sold anonymously for £250 with the identity of the artists only reveled on delivery to the buyer.

Another exhibit Kate saw involves 10 unique masks created by the likes of Dame Vivienne Westwood and milliner Philip Treacy which are also being sold.

After her tour of the various works, Kate mingled with guests and donors of the Gallery before attending the Gala dinner. Guests included Alexa Chung, Samantha Cameron, Erdem, Princess Diana's brother Earl Spencer and his wife Karen, and Donna Air, the girlfriend of Kate's brother James Middleton.

The Gala is fundraising for the 'Coming Home' project which works to return iconic portraits to places that are special to them for a loan of three years. It will enable sitters such as Sir Walter Raleigh to return to Dorset, the Brontë sisters to Yorkshire and David Beckham to Essex.

This is the second Gala that the Duchess has attended since becoming their patron in 2012. In 2014, she attended the Gala wearing her ink-blue Jenny Packham gown with the Queen's Nizam of Hyderabad necklace.

It is a patronage that suits Kate well considering her long-time love for photography and art. The Gallery boasts a collection of portraits of historically important and famous British people, and last year, photographs of the Duchess herself appeared on their walls to mark the Vogue centenary issue.
