It's only been days since Meghan Markle, Duchess of Sussex, and Prince Harry were married in their elaborate ceremony at Windsor Castle, but they are already hard at work! Today, the royal family stepped out at Buckingham Palace for a garden party hosted as part of the Prince Charles' 70th birthday celebrations, though his birthday is not until mid-November.

Harry and Meghan, who enjoyed only a brief getaway following their wedding, returned to duty today, delaying their honeymoon to honor Prince Charles. Prince Harry spoke, thanking and welcoming the 6,000 guests at the garden party celebrations. Meghan, in accordance with royal protocol, wore pantyhose underneath her blush sleeved sheath dress with a sheer neckline. She paired the design with a slanted hat by Philip Treacy.
