The dress appears to be the same one that Kate recently wore to a Platinum Jubilee party in early June.

Below is a photo of the duchess wearing the same dress last month, as posted on the Duke and Duchess of Cambridge’s Instagram account.
Kate seems to be on something of a polka-dot dress kick, as the royal recently wore a white and brown polka-dot dress ― also by Alessandra Rich ― to the Royal Ascot last month.

Rich has long been a favorite designer of the royal. Back in 2018, the duchess wore a navy polka-dot dress with an oversized white collar from the label for an official portrait to mark Prince Charles’ 70th birthday.
She later donned the same dress again in May 2019 for an exhibit in Bletchley, England, marking the 75th anniversary of D-Day.
