Meghan Markle completed one of her last big royal firsts tonight: her first work engagement alone, without Prince Harry, the Queen, or any other member of the family accompanying her. She chose to wear a black Givenchy dress with a leg slit—a designer choice that has a lot of meaning packed in it. Meghan has been wearing Givenchy, designed by Clare Waight Keller, for all her big royal firsts.

Givenchy, of course, was her wedding dress designer:

Givenchy was her choice for when she did her first solo engagement with the Queen at the beginning of June:

Givenchy was the designer of her dress for her first Royal Ascot in June:

Givenchy was what she wore when she arrived with Prince Harry for their first international trip to Ireland in July:

She also wore it again during the second day of their royal tour:

And Givenchy was her choice again today when she did her first event alone:

If the Duchess of Sussex keeps this up, expect to see Givenchy on her first major, multi-country royal tour next month when she and Harry tour Australia, New Zealand, Fiji, and the Kingdom of Tonga.
