The Princess of Wales donned a Philip Treacy-designed hat during the Tuesday, May 20, event alongside husband Prince William. Kate wore her hair in an updo, while maintaining the attention on the detail of the creme-colored hat that featured a large, floral embellishment.
The fashion piece looked familiar on Kate, as she first wore the hat during Meghan and Harry's royal wedding in 2018. Life & Style compares photos of Kate's fashionable moments with the hat at the 2025 Garden Party and Harry and Meghan's wedding.
