The Prince and Princess of Wales have led tributes to celebrate the Duchess of Edinburgh’s milestone 60th birthday. Sophie, who joined the royal family more than 25 years ago upon her marriage to Prince Edward, marked the occasion privately on Monday at home with her husband, the Duke of Edinburgh.

Sophie, the Duchess of Edinburgh, rang in her 60th birthday by posing for an official portrait in a white Proenza Schouler coat paired with a brown turtleneck and wide-leg bright green pants. The elegant yet modern look paired with a bold splash of color–a welcome departure from the conservative power suits she wore in her early royal days–showed just how far Duchess Sophie’s style has come over the years.
