The royal may have been sending a message to a sister-in-law, with Meghan having chosen Givenchy as the designer of her wedding dress back in 2018.
Prior to stepping down from royal duties and welcoming two children, the former actress wed Harry in Windsor on May 19, 2018.
The Princess of Wales’s decision to wear the French luxury brand also represents a notable fashion moment – with the royal having typically favoured British designers for major royal occasions such as State Banquets.
The future Queen also paired the elegant gown with the Lover’s Knot Tiara – marking her first tiara appearance since November 2023.
Kate, who married into the Royal Family in 2011, has worn the iconic Lover’s Knot Tiara on at least 12 occasions – which has made it one of her most frequently chosen royal headpieces.
Kate’s attendance was only confirmed on Tuesday afternoon, as her participation in major events continued to be confirmed at the last minute, as she continues to safeguard her health following her cancer battle.
Prior to their appearance on Tuesday evening, Kensington Palace has released a new picture of William and Kate as they prepared to attend the French State Banquet at Windsor Castle.
