Many may see the style as a little old-fashioned because it was regularly worn by the exquisitely elegant American First Lady Jacqueline Kennedy, back in the '60s. When the politician's wife wore it, it became an instant hit, particularly as she often donned it for formal occasions. This had a knock-on effect, and many would say it redefined First Lady fashion; she paved the way for more formal, classic ensembles.
One of the smallest formal hats money can buy, it famously 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 wore this brown pillbox hat by Lock&Co in 2015
We all know that Princess Kate is partial to a variety of headpieces, from floral fascinators to chic headbands, but there's one hat that really is her crowning glory, and that's the pillbox. Take a look at her most memorable moments with the accessory...
In 2015, Kate wore a brown velvet pillbox hat for the annual St. Patrick's Day parade. It was the perfect accompanying item and looked amazing nestled onto her mocha-toned curls.

The royal attended the Commonwealth Day service at Westminster Abbey that year, along with King Charles and Queen Camilla, as well as her husband, Prince William. As always, Kate nailed her outfit choice for the service, wearing a tailored blue coat dress by Catherine Walker London. She wore her hair in a long, loose style with coiffed curls, and her Sean Barrett hat was the perfect accompanying headgear.
At the Commonwealth Day service in 2025, Kate chose to don this pristine pillbox hat in the same striking red as her Catherine Walker coat. The ruby red hat was a bespoke creation by former milliner, Gina Foster.
As a fashion editor who has been writing about style for over fifteen years, I would say that a pillbox hat elevates any look, bridging the gap between casual and formal dressing. It looks great with a dress at a wedding, but I would wear one with tailored items such as smartly pressed trousers and a matching blazer for a graceful ensemble.
