The Duchess of Cambridge attended the Portrait Gala this evening at London's National Portrait Gallery in her role as Patron.
Before the dinner, Kate toured some of the exhibitions in the gallery.
The Duchess has been Patron of the National Portrait Gallery since 2012, and this was the second fundraising Gala she has attended in her role - the first was back in 2014.
The Duchess looked elegant for the black-tie event in a "new reveal" green lace gown by Temperley London.
You may recall we got a glimpse of the dress in April 2016 when Kate was snapped arriving at Buckingham Palace for the Queen's private 90th birthday dinner.
The bespoke green dress appears to be a fusion of the British designer's 'Ariel' Lace Maxi Dress and 'Amoret' gown which Kate owns in black. Alice Temperley has rendered the 'Ariel' silhouette with the lace fabric of the 'Amoret'.
Here's a closer look at the identical lace floral pattern of the two gowns.
The Duchess offset the dress with her Wilbur & Gussie 'Charlie' gold glitter clutch (£195), a long forgotten piece which she has only carried on a few occasions since we first saw it 2011.
The small envelope clutch has glitter exterior and features a jewel-encrusted brooch on the front flap.
Kate paired the clutch with shoes from the same vintage. On her feet were the Jimmy Choo 'Dart' glitter sandals.
The strappy platform heels have not been seen since their debut at the Malaysian State dinner in September 2012.
Kate finished off the look with a dazzling new pair of earrings by her go-to jeweler, Kiki McDonough. The Candy Pink Tourmaline and Green Amethyst Drop Earrings feature stunning pear drop green amethysts and pretty round pink tourmalines surrounded by delicate diamonds set in 18ct yellow gold. The earrings originally retailed for £8,900 but have now been reduced to £5,340.
The Duchess of Cambridge visited the Royal College of Obstetricians and Gynaecologists today for the launch of a series of maternal mental health films titled 'Out of the Blue'.
The films were produced by the charity Best Beginnings in conjunction with Heads Together, a campaign spearheaded by the The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry.
The Duchess of Cambridge spoke at the launch, and shared her experiences on motherhood. You can read the full speech here.
Kate brought back the orange and cream gingham check separates by Eponine London for today's solo engagement.
She debuted the two-piece set for a visit to the urban youth charity XLP in March 2016.
Kate opted for lighter accessories on this occasion and supplemented the outfit with her beloved combination of Ginavito Rossi praline suede 'Gianvito 105' pumps and LK Bennett 'Nina' clutch.
The Duchess finished the look with her Kiki Morganite Cushion Drop & Diamond Earrings.
Following a day of engagements in the heart of the French capital, the Duke and Duchess of Cambridge capped off their royal visit to Paris on Saturday by attending the Wales v France 6 Nations Rugby game at the Stade de France.
William, as Patron of the Welsh Rugby Union sang the anthem alongside Kate.
Kate wore red in support of the Welsh team, who unfortunately for the royal couple lost the match.
She first wore the double-breasted coat by Carolina Herrera in Yukon during last year's royal tour of Canada.
Kate kept the same Cartier 'Trinity' earrings and Chanel purse from earlier in the day.
The Duchess finished the outfit with her black Cornelia James 'Imogen' gloves.
I hope you've all enjoyed following Kate's sartorial choices for the whirlwind visit to the fashion capital of the world! I think she was on-point for every occasion and I was thrilled to finally see the Duchess in Chanel! I'll leave you with a collage of all the outfits. Vote for your favourite one below:
The Duchess of Cambridge started her second and final day in Paris in a stunning number by iconic French fashion house, CHANEL.
For a day of engagements in the fashion capital of the world, Kate wore a black/white/red cotton tweed coat from the designer's RTW Spring/Summer 2017 Pre-Collection as suggested by @PerthsFashion.
The Duchess also accessorized with luxury items from the French fashion house. She carried the Chanel Calfskin Flap Bag with Enamel Handle in burgundy. The quilted leather bag is from Chanel's Fall/Winter 2015/16 collection and had a retail price of US$4,200.
She defined her waist with a black Chanel calfskin and gold metal leather belt featuring the signature CC logo.
Kate continued the French luxury theme to her jewellery.
She wore a new Cartier necklace and earrings from the jeweller's 'Trinity' collection (ID by @AnnieElizabethN), and also her trusty Cartier Ballon Bleu de Cartier Small Stainless Steel Bracelet Watch.
On her feet were her Tod's Burgundy Fringed Leather Pumps.
The Duke and Duchess of Cambridge began their day at Les Invalides, a site that supports veterans, as well as victims of the recent Paris attacks.
The next stop for the Duke and Duchess was Musée d’Orsay, an art museum on the left bank of the Seine. It is housed in a former railway station that was built between 1898 and 1900.
The royal couple then headed to the Trocadéro near the Eiffel Tower to visit “Les Voisins in Action”, a event which highlights the strong ties between the young people of France and the UK.
And finally, they posed for a photo in front of Paris' top tourist attraction, the Eiffel Tower.
For William and Kate's final event of Royal Visit Paris, they will attend a Wales v France 6 Nations Rugby game at the Stade de France. We expect Kate to make a wardrobe change for the occasion. Stay tuned!
The Duke and Duchess of Cambridge joined the Irish Guards at Mons Barracks in Aldershot for the annual St. Patrick's Day parade.
The Duchess presented shamrocks to members of the regiment.
She also gave one to the Irish Guards mascot, Domhnall - an Irish wolfhound.
Kate looked festive in a bespoke forest green Catherine Walker coat.
The double-breasted design bears a resemblance to the red Catherine Walker 'Russian Greatcoat' she wore on arrival in New Zealand for the royal tour in 2014. The new coat is fashioned with gold buttons, and a contrasting velvet collar and cuffs.
Green has been the colour of choice for Kate at this traditional event, except for when she surprised us in 2015 by wearing a chestnut brown ensemble. You may recall that the Duchess was absent from last year's parade which didn't go down well with the public and the media.
Kate extended the green theme to her accessories. She complemented the outfit with her Monica Vinader Green Onyx Siren Wire Earrings and deep green Lock & Co hat by Sylvia Fletcher.
Kate's new suede pumps are a bespoke pair from Emmy London.
They are the 'Rebecca' model in greenery suede available via Emmy's bespoke service.
In addition to new shoes, there was also a new clutch bag.
18 MAR 2017: ID UPDATE
The green croc-embossed clutch bag is by a Polish brand, Etui which was available at Topshop (sold out) - thanks to the WhatKateWore community for the ID! You can find the crocodile-effect clutch on eBay in a range of colours.
Here we catch a glimpse of the Cartier Ballon Bleu Watch.
As expected, the Duchess donned the Irish Guards gold shamrock brooch. The three-leaf brooch belongs to the regiment and they loan it to Kate for the occasion.
Here's a closer look at Kate's beautiful up-do.
Next up, Kate will fly over the English Channel to commence a two-day visit to Paris with Prince William! They are due to arrive around 4:30 pm (local time). On arrival in Paris, The Duke and Duchess will meet with French President François Hollande at the Élysée Palace. See you then!
