Queen Elizabeth II wore a cerise pink coat and a matching hat during a visit to the Royal Mail delivery office near her home in Windsor Castle on Wednesday. She was accompanied by Prince Philip for the 500th anniversary of the Royal Mail ahead of her 90th birthday Thursday. Celebrations started early for the royal who was serenaded by the Royal Mail choir singing Happy Birthday.

The punctual queen arrived bang on time for the engagement, dressed in a cerise coat and white silk floral patterned dress by couturier Stewart Parvin. Her coat featured long sleeves and chunky silver gray buttons in the front and the sleeves. Elizabeth paired the outfit with a matching hat by Rachel Trevor-Morgan.

The asymmetrical hat featured floral embellishments and a silver ribbon bow. The queen accessorized with a three-string pearl necklace, matching earrings and a diamond brooch. The queen, who is known as one of the most popular fashion icons in the world, paired her look with white gloves and her black and gold patent pumps.

Elizabeth carried her trusty small black handbag by her go-to London brand Launer, a favorite of hers since the 70s. It featured a patent finish and signature gold logo. She finished off her daytime look with a slick of pink lipstick.

Prince Philip looked handsome in a black suit that he paired with a crisp white shirt and blue printed tie. He completed his look in a pair of black lace-up shoes. Elizabeth, meanwhile, was presented with a bouquet of flowers by Bob Hartley , who has been a postman for 53 years and five months, making him Royal Mail’s longest-serving employee.

She was also given flowers by four children picked out of the crowd, including 18-month-old Charlie Capper. Royal Mail announced during the visit that the Windsor delivery office is to be renamed The Queen Elizabeth Delivery Office, and the Queen unveiled a plaque with the new name. She was also shown the special commemorative stamps celebrating her birthday that has the picture of Prince George on it.

She was given the first in a limited numbered edition of 90 framed sets of stamps issued for special events during her reign. She was also given a sterling silver hallmarked fountain pen. The birthday gift drew a laugh from Philip, who jokingly asked the Royal Mail staff: “Are you sure you can afford it?”
