Praised for her warm, approachable nature, the Duchess of Edinburgh has also carved out a reputation as a style icon, marked by a striking evolution in her fashion choices.
What should have a joyous occasion came distressingly close to a royal tragedy - with a highly traumatic birth leaving the Duchess Sophie reportedly just '15 minutes away from death'.
With the new season comes a fresh wave of fashion collections - and one brand making a notable impression is John Lewis, with a range that embodies understated luxury.
Sean Smith wrote in his book, Sophie: Saving the Royal Family: 'Sophie was a practical listener and observer and she absorbed how to be a proper Royal by watching the Queen at work.'
Penelope Chilvers, renowned for its luxury footwear handcrafted in Spain, specialises in timeless designs built to last - shoes that are as practical as they are eye-catching.
