Meghan Markle is ticking off royal milestones at a rapid pace.

After attending her first solo event with the Queen last week, Meghan joined Prince Harry and some of her in-laws at the annual Royal Ascot opening day on Tuesday.

The Duke and Duchess arrived at the racecourse, an hour outside London, in a carriage. They mingled with the Queen, Prince Charles and Camilla Parker Bowles.

Meghan wore a Givenchy white suit dress, the same designer of her wedding gown, and a white and black racing hat.

Harry nailed the formal dress code, too, in a vest and top hat.

We’re set to see a lot more of Meghan and Harry this week – it’s understood they’ll attend every day of the historic racing festival, which runs June 19 – 23.
