Lady Louise Windsor joined her parents the Duke and Duchess of Edinburgh as she rode in a carriage for Trooping the Colour on Saturday.
Louise wore her sandy blonde locks in a low chignon to allow for her stunning blue floral hat. We also loved her intricate pearl drop earrings.
The young royal, 20, was seen wearing a white dress with a blue floral design, the 'Kumiko Iris Silk Dress' from Suzannah London. Her gown had a high neckline and long puffed sleeves.
Her mother Duchess Sophie, 59, looked radiant in a canary yellow Beulah London gown with a rounded neckline to match her netted fascinator from Jane Taylor.
Lady Louise hasn't been spotted at a royal engagement since Christmas Day when she was seen at the annual festive service at Sandringham. The royal has been busy with her studies at St Andrew's University in Scotland where she is reading English Literature.
She made an appearance at the Royal Windsor Horse Show alongside her parents where she rode in a carriage in a straw hat with a silk hair tie elevating her look.
Lady Louise has previously been seen alongside her brother James, Earl of Wessex and her parents at Trooping the Colour.
In 2022 Louise wore a coral floaty dress with pale flowers printed all over. She wore a beige hat with flower detailing.
The royal also wore a cropped white jacket as she waved from the balcony.
