What a summer Harriet Phillips is having. She officially joined the Royal Family when she married Peter Phillips in June, and since then the newlyweds have attended events such as Royal Ascot, the Championships at Wimbledon and various polo matches.
From her beautiful lace Emilia Wickstead wedding gown to creations by Suzannah London, we certainly know she's got good taste in dresses, and the dress she wore for the DMMI Royal Charity Polo Cup last month was another triumph.
It's the now sold-out Beulah Aybra Cornflower Linen Dress, which cost £395. The British clothing brand is a favourite of the Princess of Wales, and Harriet added Kiki McDonough green amethyst and diamond earrings, a quirky Anya Hindmarch basket bag and Finlay London sunglasses - all of which are also very Kate Middleton-coded.
Recreate the look

Harriet's exact dress might be sold out, but this Ghost option is a close second best. The button-down detailing is extremely similar, and the pleats in the bodice really elevate it.

If you've still got a wedding in the diary this summer, you could be the 'something blue' in this Nobody's Child number. The puff sleeves are perfectly on trend, and the statement bow design at the back is a bonus.

The broderie anglaise detailing on this dress gives it a summer feel, but add a cardigan and you can wear it into autumn, too. One reviewer said of the dress: "Fitted beautifully. Perfect length and the material was soft and a lovely colour. Really flattering."

Anya Hindmarch fans would have noticed this bag a mile off. The eyes are such a fan addition, plus it's the perfect size for all your essentials, whether that's for sightseeing on holiday or a day out back home.

Finlay makes some of the best sunglasses you can buy, and the shape of these shades is really unique. Tortoiseshell is a much softer alternative to black frames, too.

These nude sandals are the ultimate leg-lengthening shoe. The heel height is really manageable, and the gold metal detailing makes them look much more expensive. I've got a couple of pairs of Loeffler Randall shoes, and I'm always impressed with how comfortable they are.
Harriet's dress is the prettiest shade of blue, and I love the flattering sleeves and raffia belt, which picks up on her bag. It's 100% linen, so it's breathable for the last weeks of the summer, and you could really experiment with some of the fashion colour trends 2026.
Chocolate brown paired with pale blue is a particular favourite of mine, or you could even go for something really unexpected, like a pair of leopard print shoes.
You'll notice that a lot of high street stores - like M&S and Phase Eight - are starting to drop their autumn collections this week. But with the sun still shining, Harriet's pretty midi is a reminder that, firstly, I'm not ready to give up summer dresses quite yet, but also that, styled the right way, a dress like this will be incredibly useful into next season.
