Christmas is here, it's official. And how do we know? Because the Princess of Wales' annual Christmas carol concert has taken place on Friday, 5th December, of course! The stunning royal was supported by not only her husband, Prince William and their three children, Prince George, Princess Charlotte and Prince Louis, but also her little brother James Middleton, and his gorgeous wife, Alizée Thévenet.

Although there's no official dress code for this memorable event, attendees tend to go into full-on festive mode, rocking Yuletide colours such as green, rich reds, navy blues and burgundy. Princess Kate sported a forest green coat by Catherine Walker, and her mother, Carole, rocked a tartan navy and green coat by House of Bruar. Kate's cousin-in-law, Zara Tindall, also turned heads in navy blue in the form of a coat by Alice & Olivia.

Alizée looked so stylish in her checked outfit

Alizée defied tradition, however, choosing an oversized co-ord by super cool brand Sezane. Her 'Gabriel' coat was emblazoned with beige, black and camel checks, and the matching trousers, known as the 'Ciara', were designed in the same fabulous, Sloane Ranger style print. So chic! We love the slightly baggy look, too; it's very Gen Z and gives the mother-of-one a seriously modern, cutting-edge stance.

Alizée's co-ord by Sezane is a timeless style

As a fashion editor who has been writing about royal style for over eight years, I loved how she expertly teamed her look with a vintage-look, pie crust blouse, and suede boots in the same tone as her co-ord.

 I also spied her contrasting bag by Longchamp - the '3D S' handbag' in burgundy. With her 'clean girl aesthetic' makeup look, the 36-year-old looked understated yet glowing.

Alizée wore a H&M dress at Lady Gabriella Windsor's wedding in 2019

One of my favourite looks that Alizée has ever worn has to be when she attended Lady Gabriella Windsor's wedding in 2019. Various members of Princess Kate's family made an appearance at the nuptials, which were held at Windsor Castle. Among them was Alizée, who was then known as the girlfriend of James. Despite the fact that many guests wore designer clothes, Alizée wowed onlookers in an amazing statement dress, which turned out to be a high street steal - a £49.99 number from H&M.

Alizée teamed her dress was a straw boater hat

Alizée's midi dress featured a Versace-style, chain-print pattern, a V-neckline, and a wrap-over front. The tie belt, long sleeves, narrow buttoned cuffs and pleated skirt were effortlessly stylish - as was her straw boater hat and nude high heels.
