How Princess Kate is reinventing 'old lady' fashion in 2026

Fashion editor and stylist Matilda Stanley agrees. "Kate has such a signature look; whether she is on the red carpet or doing a royal visit, the Princess looks polished at all times, and her elegant outfits always manage to bridge perfectly between vintage and modern. It's a clever styling trick, and Kate's choice of 'old lady' outfit rules means that her looks appeal to fashion fans of all ages."

"A real go-to for the royal ladies is the coat dress, which is often seen as a little frumpy or outdated, but Kate regularly pulls off the risky piece with plenty of 'wow' factor," Matilda muses. "The key to keeping this retro-style outfit looking chic is to opt for designs with a structured shape and definition like a nipped-in waist and flared skirt, and Kate will often complete her look with a pair of shiny heels and some oversized jewels, which work well to bring a contemporary spin to her outfit."

Vintage jewellery is really having a moment right now, and has fast replaced the subtle, quiet luxury jewellery trend of 2025. There is just something about wearing an item that is encased with history, that gives a unique spin to any look. We all know that Kate loves jewellery like this; she's renowned for her love of extravagant jewels embedded in tradition. From diamond drop earrings belonging to the late Queen Elizabeth, to her oval-cut sapphire engagement ring that belonged to her mother-in-law, the late Princess Diana, Kate knows that unique items like this will always look timeless.

Knitted separates have grandma written all over them, and Kate has been a longtime lover of beautifully made, woollen items. As recently as last month, Kate paid a visit to the National Curling Academy in Stirling ahead of the Winter Olympic Games, wearing a grandma-core waistcoat featuring a Fair Isle-style heart design. The soft woollen number was styled over a roll-neck jumper by Zara and teamed with a black A-line skirt and flat boots from Tod's. The nostalgic piece was feminine yet cosy, and we're sure she will bring it out, season after season.

The pillbox hat may be loved by content creators in 2026, but it was originally worn by American First Lady Jacqueline Kennedy, back in the 60s. One of the smallest formal hats on the market, it has no brim and sits smartly at the back of the head. Head Millinery Designer at Lock & Co, Awon Golding, previously told HELLO! that the iconic style "gives a glamorous nod to traditional millinery, whilst also adding a romantic touch to any modern outfit."

Kate has a plethora of these hats, and they always give her outfit a vintage feel that oozes elegance. You know your grandmother has one of these nestled in her wardrobe somewhere.
