When It Comes To Fashion, Princess Diana And Kate Middleton Have One Thing In Common

Catherine, Duchess of Cambridge, and the late Princess Diana are known for their stylish royal looks, but the connection between their wardrobes goes even further.

For Princess Di, go-to outfits included statement gowns, like her iconic revenge dress, per Vogue, and tailored suits, as pointed out by Marie Claire. And, many times, these ensembles were by Catherine Walker, a French-born, London-based designer.

Kate Middleton has had amazing fashion moments, too. She can often be found in a structured coat dress in hues like burgundy, gray, light blue, and (more than once) emerald green, via Town & Country. These pieces are also all by Walker.

Per the company's website, Catherine Walker & Co was established by Walker and her husband, Said Cyrus, in 1977. Over the years, the garments have been seen on other notable celebrities, such as Joely Richardson, Olivia Williams, Lady Isabella Hervey, Tara Palmer-Tomkinson, Lady Gabriella Windsor, and Jodie Kidd, reports British Vogue.

Catherine Walker was a favorite of Princess Diana and is now loved by Kate Middleton, too

According to Newsweek, Catherine Walker & Co was a top source for dresses and coat dresses in the 1980s. Before that, though, Catherine Walker worked under her label, the Chelsea Design Company, and produced fashionable maternity clothes. 

Therefore, when Diana was pregnant with Prince William, she turned to the designer, and the rest is history. Walker went on to provide the People's Princess with more garments than any other designer. Even the dress Diana was buried in was by Walker, as reported by The New York Times.

Walker died in 2010, but her brand, now led by her husband, is still a success, with its website stating that it "proudly maintains its position as a leading British couture house." In fact, when Kate Middleton and William got married in 2011, Middleton's mother, Carole, wore a blue silk suit from Catherine Walker & Co.

Since then, the Duchess of Cambridge has commissioned the brand for hundreds of designs, following in the sartorial footsteps of her late mother-in-law.
