For the occasion, the Duchess of Cambridge re-wore a beautiful pastel blue dress made by her private dressmaker.
The Duke and Duchess of Cambridge were joined by the Earl and Countess of Wessex, Princess Beatrice and the Duke and Duchess of Gloucester who also attended the annual garden party.
Kate opted for a summery midi dress which she combined with a matching hat.
A pair of pastel blue stilettos and a matching clutch bag finished the Duchess’ stylish look.
The gown is the same one the Duchess wore for Prince Charles’ 50th anniversary of his investiture.
Back in 2019 when the Duchess first wore this design, the Palace confirmed the dress was custom made by Kate’s private dressmaker.
The pale blue dress featured a high collar, full skirt and loose sleeves with a fitted cuff.
Royals fans took to social media to praise the royal’s outfit.
