Kate Middleton's 42 most stylish looks to celebrate her fashion evolution on her 42nd birthday - photos

As she celebrates her 42nd birthday on Tuesday, the Princess of Wales has been ushering in a new phase of her style evolution. But while the future Queen has surprised us with her wardrobe choices since taking on her new royal title, she has also remained true to some tried-and-tested fashion options – and we've chosen our favourite 42 of her recent regal looks. 

These show her loyalty to Catherine Walker, long one of her go-to labels, which created the stunning cape coat Kate wore to welcome South Korean President Yoon Suk Yeol and First Lady Kim Keon Hee to London last November. Her choice of red was deliberate, echoing South Korea's flag, following her green embellished Andrew Gn dress for Trooping the Colour last year, a tribute to her role as Colonel of the Irish Guards. A master of sartorial diplomacy, on royal tours she tends to wear pieces by local designers, opting, for example, for a dress by Mumbai-born Naeem Khan in India in 2016.

Other elements of classic Kate include block colours, such as the royal-blue coat – another Catherine Walker design – worn for last year's Commonwealth Day. When it comes to her silhouette, Kate favours an A-line, as seen on the lemon Emilia Wickstead dress worn during the Platinum Jubilee in 2022, although her hemlines have grown noticeably longer. Another change has seen the Princess experimenting with prints, adding an array of new names to her repertoire, including Holland Cooper and Eponine London. 

While Kate has long loved a business casual look, from Zara blazers to Gucci pussybow blouses, 2023 was the year of the power suit, with the Princess even embracing her own "Barbiecore" moment in a pastel pink trouser suit from Alexander McQueen. Sarah Burton, the label's former creative director, is another of Kate's favoured designers, as is Jenny Packham, for state events and red-carpet appearances. Showstopping looks from them include her shimmering gold gown by the latter for the 2021 premiere of No Time to Die and the embroidered McQueen dress and bespoke headpiece for the coronation. 

To the delight of royal watchers, Kate rewears many of her gowns, often with new touches, such as swapping the belt on a McQueen gown first worn in 2011 to give it a fresh look on the red carpet ten years later. Other accessories include headbands – a must-have since Kate sported a pearl-adorned Jane Taylor piece at Prince Louis's christening in 2018 – while last year, she surprised in black opera gloves with an upcycled McQueen gown at the Baftas. 

A constant in Kate's wardrobe, however, is her love for mixing high street and designer pieces. Take her outing to the Natural History Museum in London in 2019, when she matched Warehouse and Jigsaw with the pièce de résistance – a burgundy Chanel handbag. She is also a fan of the Breton top and her trusty Superga and Veja trainers. Nor is she afraid of sneaking denim into her royal outings – a pair of mom jeans from & Other Stories flew off the shelves when she wore them in 2021. She may have evolved from her tea dresses and nude heels, but the Kate Effect is still going strong.
