Every supermodel is copying Princess Diana's favourite street style accessory right now

Forget achingly chic It-bags and dreamy footwear, the accessory that seemingly every A-lister is rocking right now is the humble baseball cap. Hat trends come and go, but the staple cap is something of a timeless classic.

Royal style icon Princess Diana couldn't have predicted the lasting impact that her chic athleisure ensembles would come to have on the modern street style – currently #princessdianastyle boasts an impressive 44.3m views on TikTok.

Avid fans of the princess' outfits will recall that she strongly favoured graphic sweatshirts, cycling shorts and chunky trainers in the late 1980s and early 1990s. Even when nipping to the gym, she made her style a priority – as if we couldn't love her any more.

The princess often wore a navy baseball cap 

One of her most-adored accessories was a navy camp adorned with gold embroidery. The princess wore it constantly, styling it with a blazer and mid-calf brown leather boots at school drop off as well as with jeans and her iconic balloon sweatshirt at the polo. Versatile – we very much approve.
