In addition, Oriona Robb, a fashion expert and stylist claimed: "Meghan Markle's decision to wear around £200,000 worth of clothes and jewellery at the Invictus Games may have been a deliberate choice to make a statement and showcase her personal style.
"As a style icon, she may have wanted to convey a sense of luxury and sophistication through her outfit choices.
"Additionally, Meghan could have been expressing her support for the event by wearing expensive attire, highlighting her commitment to the cause.
"On the other hand, the Princess of Wales is known for her down-to-earth nature and support for small British designers.

"Each member of the Royal Family may have their unique style preferences and ways of supporting causes through their fashion choices."
