Kate Middleton was recently photographed wearing a blue sash at this week’s state banquet. But eagle-eyed royal fans couldn’t help but notice that her sash is narrower compared to those worn by Camilla Parker Bowles and Queen Elizabeth II.

On the online forum site Quora, royal fans discussed the meaning behind the Duchess of Cambridge’s sash and said that it wasn’t actually narrower than Camilla’s sash. However, it was indeed narrower compared to the sash of Her Majesty.

Alison Hill, a resident of the United Kingdom, said that some royal fans might have thought Middleton’s sash was narrower because of an optical illusion. Her sash also had a red and white border, which means that the blue color is not emphasized.

“The difference is due to the orders they represent. The Duchess of Cambridge’s sash is the riband of the Royal Victorian Order; the Queen’s sash (also worn at the dinner by the Prince of Wales and the Duke of Cambridge) is the riband of the Order of the Garter… The Order of the Garter is senior to the Royal Victorian Order so someone who is a member of both will wear the riband of the Garter except when the occasion specifically relates to the Royal Victorian Order,” she explained.

Chris Smith, a former high school history teacher, said that Camilla, Middleton and Sophie, Countess of Wessex, all wore the sash of the Royal Victorian Order since this is the highest honor they have received from Her Majesty.

“The Queen, Princess Anne, and Princess Alexandra all wore the sash of the Noble Order of the Garter, which is the highest honor they have received. Note also that Charles, William, Andrew, and Edward all wore the same sash as they too are all Knights of the Order of the Garter,” he said.

Middleton, Prince William, Prince Charles, Camilla, and Prince Harry all attended the state banquet with Trump and his wife. Meghan Markle wasn’t around because she’s currently on maternity leave.
