The royal couple have left for their evening reception in a classic open-top car, where they will celebrate with 200 close friends and family.
The wedding dress and military uniform have been cast to one side.
Tonight, Meghan is wearing a cream halter-neck dress and Harry is in black tie.
The reception is being hosted by Prince Charles at Frogmore House, a country house near Windsor Castle.
Prince Harry was in the driving seat of the silver blue Jaguar E-Type Concept Zero - originally manufactured in 1968 and converted to electric power.
Ms Markle is wearing a lily white high-neck gown made of silk crepe designed by Stella McCartney, says Kensington Palace.
Her shoes from Aquazurra are made in silky satin, with nude mesh, and the soles are painted baby blue.
