Meghan Markle Stuns in Givenchy Dress as She Attends First Royal Ascot With Prince Harry

Tuesday marks the royal couple's one-month anniversary.

Meghan Markle dazzled the crowds at her very first Royal Ascot with her husband, Prince Harry, by her side. 

The newlyweds arrived at the iconic British horse racing event in an open-air carriage, accompanied by Prince Edward and his wife, Sophie, the Countess of Wessex. 

Markle, the Duchess of Sussex, wore a chic white-and-black ensemble by Givenchy that some called Audrey Hepburn-esque, while Harry donned a traditional top hat and tails. 

Givenchy is the same designer behind Markle's wedding dress.

Markle has been busy since she wed Harry just one month ago. Last week, she joined Queen Elizabeth II on an outing in northwest England, traveling overnight on the queen's luxurious train.

The trip attracted some attention for deviating from royal tradition, as only the top four members of the royal family — Elizabeth, Prince Phillip, Prince Charles and Camilla — have ridden on the train in the past.
