Meghan shared a photo of herself and Harry en route to the event, before the couple was seen walking into the black-tie gala.

​Harry and Meghan joined David Foster and his wife, Katharine McPhee, for the special evening, marking four decades of the foundation’s work. 

​Founded in 1986, the David Foster Foundation offers financial support to Canadian families with children undergoing life-saving organ transplants, helping to cover essential expenses not covered by insurance.

​Meghan and Katharine are longtime friends, having attended the same middle school in Los Angeles and performed together in local musical theatre productions during their childhood. It's reported David and Katharine helped the couple find the Vancouver Island home after leaving the UK in 2019.

For the black-tie occasion, Meghan embraced an elegant evening look, stepping out in a one-shoulder cape gown by Canadian-based label Greta Constantine. The ‘Fabrizio’ style features a body-skimming silhouette, a dramatic asymmetric cape, and fluid draping throughout.

She carried her Gucci 'Broadway' Butterfly Embellished Satin Clutch and stepped out in her black Stuart Weitzman 'Nudist' sandals.

The Duchess completed the look with Princess Diana's Butterfly Pavé Diamond Stud Earrings.

She also posted an Instagram Story of herself dancing around the kitchen in her pyjamas, looking ready to celebrate her special day with her family.

Meghan is wearing a "It's Giving Mrs" t-shirt. These can be found on Etsy. 

Her pajama bottoms appear to be by Eberjey (she has a set in red).

Meghan's festive headband is from Target. 

She also has on her Logan Hollowell 'Lovers Duet' Necklace​.

As Ever also posted a birthday message. The photo is from the May 2026 shoot which we covered in this post. To recap, she's wearing a Céline Stripped Cropped Shirt and Anine Bing 'Brie' Jeans.

In the video, Meghan wears a crisp all-white ensemble featuring the Reformation 'Tate' cross-neck linen top and the POSSE 'Emma' linen pencil skirt.

She accessorised with a tortoiseshell headband and black Balenciaga BB0323SK sunglasses. The headband has been suggested to be by France Luxe, though it is a common style available from numerous retailers.

Meghan embraced a laid-back style in a relaxed-fit Brochu Walker 'Gaia' Knit Tee in Terra Marl, paired with crisp white Jenni Kayne 'Newport' shorts.

She accessorised with her Logan Hollowell 'Lovers Duet' Diamond and Emerald Chain Necklace​.

On Meghan's feet were a new pair of velvet loafers featuring a tassel accent.

They are the ​J.McLaughlin 'Cecily' Velvet Tassel Loafers in Navy Blue.

Meghan serves as an executive producer of the documentary alongside Prince Harry through Archewell Productions. Cookie Queens is a coming-of-age documentary that follows four young Girl Scouts—ages 5 to 12—as they navigate the highly competitive annual Girl Scout Cookie season, each hoping to become a top-selling "Cookie Queen."

Meghan struck the perfect balance between polished tailoring and effortless ease, styling an ecru Akris Double-Breasted Linen-Wool Double-Face Jacket with crisp white Tracy James Upper Village Jeans.

Layered beneath the blazer was her Anine Bing 'Amani' Tee in Off White Cashmere Blend.​

On her feet she wore the Hermès ‘Santorini’ sandals.

She also debuted a couple of new rings, mixing them with familiar favourites from her jewellery collection. On her left middle finger she wore a Logan Hollowell Aura Sleeve (Gen 4 & Gen 5) which pairs with the Oura smart ring. 

On her right hand was the Logan Hollowell Leo Constellation Ring.

Meghan is dressed casually in a navy sweater with her Anine Bing 'Kate' jeans.

What Meghan Wore suggests the sweater could be a past-season J.Crew 'Rollneck' sweater, as this fisherman-inspired style is a signature of the brand's knitwear collection, with a slightly updated design released each year. The best match is the J.Crew Unisex 1988 cotton rollneck sweater.

Her specs are the $69 Blenders 'Shadow' aviator sunglasses.

She appears to be holding her ​Bottega Veneta Intrecciato Slim Long Wallet.

OneOff is suggesting that the headband may be the Jennifer Behr 'Tori' Velvet Headband. While it is a possible match, their past product identifications have not always been accurate, so this should be considered unconfirmed.

In a black and white photo while out for dinner, Meghan is seen wearing a Heidi Merrick 'Finny' Cardigan in Noir.

Her jewellery includes the Logan Hollowell 'Lovers Duet' necklace and Logan Hollowell Leo Constellation Ring.

MeghanWoreIt suggests the Duchess could be wearing the ​Hunza G Square Neck Swim in Black. On her feet are her black Saucony 'Cohesion 18' Sneakers.

In the poolside photo with her dog, Mamma Mia, Meghan is wearing another one-piece swimsuit, which MeghanWoreIt suggests could be the Hunza G 'Pamela' Swimsuit in Black & White. The earrings appear to be her Ariel Gordon Royal Signet Studs.

In one photo from a shopping trip, Meghan is seen wearing her Sarah Bray Bermuda 'Wildflower' Sun Hat.

She also wore the hat on a coastal walk with the family. On her feet are the Hermes 'Santorini' Sandals.

While in Althorp, Princess Lillibet wore a Doen floral print dress and was seen carrying an adorable ​Aurora Unicorn Fancy Pals Purse.

She paired her ivory Celine 2 Button Classic Blazer with a coordinating CO Ivory Cashmere Sweater Tank.​

Her trousers are the Brochu Walker 'Talia' Pant in Salt White.

For contrast, Meghan added a dark brown braided leather belt by LAUREN Ralph Lauren.

On her feet were a new pair of Veronica Beard 'Catherine' Mules in Cedar.

In a black and white shot, Meghan relaxes on the grass wearing a striped Matteau shirt paired with her linen Posse skirt, accessorized with what appears to be her signature Sarah Bray sun hat.

One photograph captures Meghan effortlessly pulling off a double-denim look by Tracy James.

In a throwback to March 2017, Meghan is seen with Harry wearing her Nike 'Flex 2016 RN' running shoes.

A second photo captures the young princess in the garden, gently touching an agapanthus bloom.

Meghan looked effortlessly chic in an olive-toned outfit, styling a new cotton sweater by Loro Piana with her Jenni Kayne 'Riley' trousers. 

She tied the whole look together with a contrasting tan Lauren slide-buckle leather belt, while her Cartier 'Juste un Clou' necklace provided the perfect polished finish.

Princess Lilibet is seen wearing the cream Cult Gaia 'Lola' Dress, which was first identified in March in a behind-the-scenes video for As Ever.
