Royal fans were delighted to catch a glimpse of the Princess of Wales on Sunday! The royal smiled jovially at passers-by as she joined her family for a church service in Balmoral following the news of her brother-in-law Prince Harry's return to the UK.

Kate was pictured arriving by car alongside her husband, Prince William, and their three children to attend a Sunday service at Crathie Kirk, near where the royals have retreated from the limelight to spend their annual summer break at Balmoral Castle in Aberdeenshire.

Kate, 44, was spied in the passenger seat, and even though we only observed a small part of her outfit, it was clear she had chosen a gloriously chic ensemble for the occasion. The royal donned a beautiful new Holland Cooper 'Audley' lace blouse, which she layered with a tweed coat, Ralph Lauren earrings, and perched on her head was one of her most instantly recognisable hats - the 'Betty Boop' style by Lock & Co.

Princess Kate's 'Pillbox' hat pact

Kate's 'Betty Boop' hat is categorised as a pillbox due to the structure. It received its namesake because it was crafted in the shape of an old-fashioned pillbox. Jacqueline Kennedy, the First Lady of the United States from 1961 to 1963, often wore the style, and her timeless elegance made it incredibly sought-after.

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."
