Queen Elizabeth II wowed in a spring grass green coat and matching hat by her dressmaker Angela Kelly as she stepped out of Windsor Castle to rapturous cheers and applause on her 90th birthday Thursday. Thousands of fans lined the streets to see the monarch on her special day, and sang “Happy Birthday” for her. Her husband of 68 years, Prince Philip, the Duke of Edinburgh, was by her side on her big day.

The 90-year-old royal’s coat featured a high neck, long sleeves, button down detailing and green buttons on the sleeves. It also had oversize pockets. Elizabeth accessorized her outfit with her favorite three-string pearl necklace, matching earrings and a diamond brooch. She wore a green straw hat with white and yellow flower and green leaf accents.

The queen wore white gloves, her trusted pair of black and gold patent pumps. Elizabeth finished her look with her favorite small black handbag by her go-to London brand Launer. The label has been her favorite since the 70s and featured a patent finish and signature gold logo. She opted for a slick of pink lipstick.

Royal watchers and fans made bets that the queen would opt for a purple dress, her current favorite hue. Besides, blue and pink followed close behind. Other color options for Elizabeth included yellow, cream, green and gold. Even Union Jack colors were not ruled out completely.

Elizabeth and Philip emerged out of Windsor to the Coldstream Guards band playing the national anthem. She and her husband were both seated in their burgundy Bentley. After a brief chat with the Mayor of Windsor, she carried out a walkabout of the town.

The nonagenarian was presented with countless bouquets of flowers, while crowds waved their Union Jack flags and continued to sing happy birthday. She met all her fans, including royal superfan Terry Hutt. Elizabeth then officially opened The Queen’s Walkway.

The royal couple continued their walk along the High Street to Guildhall, where they met Military Wives choir along with fellow nonagenarians from the surrounding area. The “Great British Bake Off” winner Nadiya Hussain presented her the orange drizzle birthday cake with orange curd and buttercream frosting.

Elizabeth and Philip then indulged the delighted crowds by getting into an ‘open state review’ Land Rover for a drive through the streets of Windsor. Later in the evening, she attended a beacon lighting ceremony in her honor along with Philip, her son Prince Charles and his wife Camilla, the Duchess of Cornwall. Elizabeth was dressed in the same outfit, but just added a headscarf for the celebrations. The day was rounded off with a private family dinner hosted by Charles at the Windsor Castle.
