STORY: Queen Elizabeth was known for her unique fashion style

Brightly colored outfits with matching hats

paired with black pumps and an omnipresent handbag

became staples for the British monarch

(Editor-in-Chief of Harper's Bazaar, Lydia Slater) "It's absolutely recognizable. It's immediately visible. It's, it's used as a diplomatic tool and you know, it's comfortable. It just fulfils all, all her requirements. And it will never go out of fashion because it's sort of never in fashion. It's just essentially itself."

At the start of the Queen's reign, her outfits were made by royal designers Hardy Amies and Norman Hartnell

who created her wedding and coronation gowns

More recently personal assistant and curator Angela Kelly planned her wardrobe

The Queen also had a large collection of brooches

which royal watchers say added a layer of meaning to her outfits

"So, for example, the Duke and Duchess of Cambridge's wedding, she wore a lover's knot brooch. And for the Duke and Duchess of Sussex, Sussex's wedding, she wore the Richmond brooch that had been given to her grandmother as a wedding gift. So both of those brooches obviously associated with weddings and with love and with happiness."
