Kate Middleton’s sister-in-law, Alizée Thevenet, and Princess Beatrice were twinning in one of summer's hottest trends at last week’s Royal Ascot.

The event, held in Berkshire every June, is a special week of races attended by the King and Queen, paying homage to their lifelong interest in horses and racing. The five-day extravaganza continues to be a platform for showcasing great outfits, designers and the royal family’s seasonal wardrobe strategy.

Kate Middleton's mom, Carole Middleton, was in attendance and was seen wearing the Two-Tone Lace-Blend midi dress from ME+EM in the peach sorbet colorway. The dress is made from lace and features yellow cord-embroidered trim. Per the brand, the dress is lined with a peach underlayer that provides an appropriate amount of coverage, making it a great choice for a day out in the sun. Carole paired her ensemble with the Claudia Mid Heel pointed-toe pumps from Emmy London and the suede Natasha clutch, also from the brand.

Carole was accompanied by her daughter-in-law (and Princess Catherine's sister-in-law), Alizée Thevenet. Alizée has been married to Catherine's brother, James Middleton, since 2021. The couple subsequently welcomed their first child together in October 2023.

For her outing with Carole, Alizée was spotted in one of summer's hottest trends, picnic core (aka gingham print). But she wasn't the only one...

Earlier in the week, Princess Beatrice also looked elegant in gingham during day one of the Ascot, opting for a pink and white peplum top from Beulah London, which she paired with the brand’s matching Arabella skirt and a light pink fascinator with a sculptural bow.

According to PureWow's fashion editors, the picnic core aesthetic is totally *in* for the summer season. Per PureWow editor Destinee Scott, the trend is “the Americana answer to the Euro Girl Summer vibe,” as traditional picnic blankets and 1950s fashion inspire it. Feminine silhouettes, checkered patterns, food-inspired fashion with fruity designs and edible motifs are the keys to nailing this trend, making it a playful, flirty look that works for a wide variety of occasions.
