While the duchess has been seen at a handful of events since Prince Louis was born five months ago, this was her first official solo engagement.

In some photos from the event, Kate appears to be helping close the auto door, which, as we all learned last week when her sister-in-law Meghan tried to do the same, is apparently a royal no-no.
She also attended the Trooping the Colour celebrations to mark the birthday of Queen Elizabeth in June, and attended the Wimbledon tennis tournament with Meghan, albeit in a private capacity, in July.
