Today The Duchess of Cambridge visited Robin Hood Primary School to celebrate 10 years of the Royal Horticultural Society Campaign for School Gardening.

The RHS programme provides children with gardening opportunities to enhance their skills & boost development.

Kate wore a mix of casual favorites for the outing.

She paired her Barbour Ladies Waxed Defence Jacket with her black Temperley London Honeycomb Tunic Sweater and black skinny jeans.

The jacket has been in Kate's closet since at least 2012, but this is the first time she has worn it for an official engagement. It's her jacket of choice when strolling in the gardens of Kensington Palace! The style has been discontinued but Barbour offers a small selection of waxed coats in their current collection:

On her feet the Duchess wore her trusty Penelope Chilvers Long Tassel Boots  (£475).  They have been a staple in Kate's closet for over a decade.  They are available to purchase directly from Penelope Chilvers.

She finished the look with her dainty KIKI 'Lauren' Yellow Gold Pave Diamond Leaf Earrings.

The Duchess of Cambridge visited The Foundling Museum in London today to learn more about the Museum's history.

The Museum explores the history of the Foundling Hospital, the UK’s first children’s charity and first public art gallery.  The Foundling Hospital, which continues today as the children’s charity Coram, was established in 1739 by the philanthropist Thomas Coram to care for babies at risk of abandonment.

She debuted a diamond-printed shirtdress by American brand, Kate Spade New York.

We are yet to find a stock image of the style but the same diamond print is available in a mini skirt, jacket and trousers:

The dress heralds from the Kate Spade New York Resort 2018 collection which will be in stores this December.

UPDATE (1 Dec 2017): The Kate Spade New York Diamond Print Shirtdress is now in stock! It retails for US$398. SHOP >

This is the second dress the Duchess has hanging in her closet by Kate Spade New York. In October last year she premiered the designer's Encore Rose Chiffon Dress.

Kate offset the printed dress with her cranberry suede Mulberry 'Bayswater' clutch bag and Gianvito Rossi 'Gianvito 105' Royale Burgundy Suede Pumps.

She finished the look with her Sapphire & Diamond Oval Drop 'Diana' Earrings.

The Duke & Duchess of Cambridge were the guests of honour this evening at the Royal Variety Performance at the Palladium Theatre in London.

This is the second time William and Kate have attended the show which is reserved for senior members of the Royal family. Their first time was in 2014.

Following a delayed arrival due to a security concern at the nearby Oxford Circus tube station, the pregnant Duchess stepped out onto the red carpet in a shimmering new Jenny Packham gown.

The dusty blue bespoke dress features a layer of illusion tulle covered in crystals and scores of tonal sequins arranged into dainty flowers.

Tonight we saw the return of the Jenny Packham 'Casa' clutch and Oscar de la Renta Platinum Lamé Cabrina Pumps. The US$690 heels are still available in limited sizes from Oscar de la Renta  and  Orchard Mile.

Kate topped off her dazzling look with diamond chandelier earrings on loan from Her Majesty.

Tonight's outfit was a slight repeat of her Paris gala look in March. The designer, dress colour, shoes, clutch, and earrings were all the same.

What did you think of this new Jenny Packham number?

The Duke and Duchess of Cambridge are in Birmingham for a day of engagements. The royal couple kicked off their Midlands tour with a visit to Jaguar Land Rover's Solihull Manufacturing Plant.

Kate revived an outfit from her second pregnancy for today's outing. She sported the Goat 'Washington' coat which she first wore in New York while pregnant with Princess Charlotte.

The mod style 'Washington' coat is made from heavy-weight black wool crepe. It has a classic swing coat shape and contrast nude tabs on the cuffs and back and decorative contrast enamel buttons. It retailed for £680 but sold out long ago.

This is Kate's second Goat Fashion repeat in a week. Last Tuesday, she donned her Goat 'Redgrave' coat for a visit to the Hornsey Road Children's Centre which she first wore in 2013 while pregnant with Prince George.

The Duchess has a penchant for Goat Fashion when she is expecting.  Earlier this month she debuted the Eloise tunic dress by the London fashion label at the Place2Be forum.  Despite the fact that Goat isn’t a maternity clothing line, the brand's signature shift silhouettes are a good choice for anyone with a changing figure.

Today Kate teamed the Washington coat with a black turtleneck top and skinny jeans. The Duchess accessorized with her KIKI Lauren Yellow Gold Pave Diamond Leaf Earrings and carried her beloved Mulberry 'Bayswater' clutch.

It's believed Kate's new black suede boots are the Russell & Bromley 'Hi Ride' Mid Heel Riding Boots (£325) - ID by Jenny via @KateMiddStyle.

For their next stop, William & Kate paid a visit to the Aston Villa Football Club at Villa Park to showcase the Coach Core apprenticeship program.

Kate changed into more casual attire and swapped her Goat coat and suede boots for her red Perfect Moment Mini Duvet quilted down ski jacket and New Balance x SB Exclusive Sneakers. She debuted both pieces at a training session for the London Marathon in February.

Following the event at Villa Park stadium,  the Duke & Duchess of Cambridge visited Acme Whistles, the world’s largest producer of whistles. Kate was back in her original outfit for this final engagement in Birmingham.

Queen Elizabeth II and the Duke of Edinburgh celebrated their Platinum wedding anniversary today. The royal couple chose to mark the occasion with a private dinner with family and their closest friends.

William, Kate and Harry arrived at Windsor Castle in Berkshire this evening for the family event.

Kate donned her Diane von Furstenberg 'Zarita' Black Lace Gown for the occasion which she debuted in November 2014 and recently wore again at the AFNCCF Gala Dinner earlier this month.

The floor-length version has sold out, but the style remains available in the cocktail length at DVF ($139.20), Nordstrom Rack ($139.97), and Matches Fashion ($174).

Tonight the Duchess teamed Princess Diana's Collingwood diamond and pearl drop earrings with a pearl necklace we have not seen on Kate before.

It is the Four Row Japanese Pearl Choker from Queen Elizabeth's personal jewellery collection. According to the blog From Her Majesty's Jewel Vault; the necklace includes four rows of pearls with a central diamond clasp in a curved shape, each side including three rows of diamonds that join at the top and bottom with marquise diamonds. According to Garrard: The Crown Jewellers for 150 Years, The Queen commissioned this from a set of the "finest cultured pearls presented to her by the Japanese government."

The Daily Mail posted a photo of Kate wearing what appears to be a black boulce coat over the top of her dress as she left Windsor Castle. What Kate Wore suggests it could be the Alexander McQueen long textured coat (US$4,450).

We will next see the Duchess on Wednesday when she joins Prince William for a day of engagements in Birmingham.
