The funeral also marked the first time Princess Charlotte wore a formal hat. The hat was a wide-brimmed style and had a smart bow at the back. It was thought to be by Jane Taylor, the brand that her mother, Princess Kate, often heads to for her incredible headbands.
Princess Charlotte's third milestone was the wearing of a brooch – the first time she has worn jewellery for a royal engagement.
