Alizée Thévenet has made her first outing of 2026, and she looked dreamy in pastels. On 28 April, the 36-year-old wife of James Middleton was spotted at the Longchamp summer pop‑up launch in Sloane Square with her dog, Isla.

The Princess of Wales' sister-in-law and French financial analyst opted for a full look from the French fashion brand.

The anchor of her look was a pair of statement jeans. The light-wash denim, which retails for £455, was covered in embroidered waves in a bubblegum pink hue. They featured a cinched waistline and a flared leg.

The jeans form part of Longchamp's Spring-Summer collection for 2026. Of the typical wearer, the brand says: "The energy of the ocean fuels her wardrobe: sun-washed colours, surf-inspired prints, and breezy fabrics like linen, cotton, and Madras. The vibe is sporty yet feminine, with strapless dresses, sporty bras, and striped polos redefining effortless summer style."

A whimsical take on surfer chic was certainly captured in Alizée's jeans, which were teamed with soft pink boots, a pale blue shirt, and a pistachio bomber jacket. She accessorised with the label's 'Looong L Shoulder bag', which retails for £480 and came in a powder blue hue.

Prior to the Longchamp event, Alizée last made a public appearance alongside her husband at the Princess of Wales' 'Together at Christmas' carol service in December 2025. Arriving in style at Westminster Abbey, the mother-of-one opted for a bold co-ord.

She wore a checked coat by Sezane featuring a collar neckline and tortoiseshell buttons down the front. It was paired with the matching cigarette trousers and suede heeled boots in a festive gingerbread colour. Her white pie crust top was the perfect layering option for the winter chill.

Fans of Alizée's style can look forward to what her summer 2026 wardrobe will offer. She certainly proved her love of pastels last year while attending Royal Ascot alongside her mother-in-law, Carole Middleton.

The French fashionista opted for a mint green gingham dress, another number courtesy of Longchamp. It featured a drawstring waist and a ruffled hem, and was styled with bottle green peep-toe heels adorned with tiny bows.

The most memorable part of her look was her grey plumed hat, which she borrowed from Carole's wardrobe. The Middleton matriarch's Juliette Botterill hat dates back to 2018, when she wore it to Prince Louis' christening at the Chapel Royal in St James's Palace.
