Kate, 37, and husband Prince William, 36, hosted the Queen as she toured the famed Chelsea Flower Show in London.
The royal mom changed from the casual culottes and sneakers that she’d worn earlier in the day to greet schoolkids for a tiered floral dress by Erdem as she met the Queen, who was joined by other members of the royal family at the annual event.
William and Kate kissed the Queen on both cheeks. Kate, who wore her hair in a braided half-updo, followed her greeting with a perfect curtsy.
The 93-year-old monarch started her visit with a stop at Kate’s woodland-themed “Back to Nature” garden, where Prince George, 5, Princess Charlotte, 4 and Prince Louis, 1, enjoyed a playdate Sunday afternoon.
The garden was created with help from the Royal Horticultural Society and designers Andrée Davies and Adam White to highlight the benefits of playing outdoors.
Earlier, when she visited with the local schoolchildren, Kate told parents at the garden that her “children played last night in a way I hadn’t imagined. They were throwing stones. I hadn’t actually thought that that was what they would be doing. They kicked their shoes off, and wanted to paddle in the stream . . . using it in a way that I hadn’t anticipated.”
