Meghan Markle was the only Royal not to wear a brooch at the RAF centenary and here's why

The Royals were out in force to mark 100 years of the RAF at Westminster Abbey yesterday, and while Meghan looked chic in a black Dior dress, you might have missed the fact that she was missing one detail: the brooch that everyone else was wearing.

Kate Middleton looked elegant in a pale blue Alexander McQueen coat, which she adorned with the Dacre brooch, a large oval adorned with jewels, which is the highest award a female cadet can achieve.

While of course, the Duchess isn't a cadet, she received the brooch as a gift following her appointment as Honorary Air Commandant of the organisation.

And she wasn't the only one with the accessory, as the Queen, the Duchess of Cornwall and even the Duchess of Wessex all wore a brooch on their left breast, while Meghan wore no accessories or jewellery, and there's a reason behind it.

She has simply not been a Royal long enough to be made an honorary member of an RAF base.

The Queen wore the Jardine Star Brooch, which is shaped like a star and surrounded by diamonds, though this is more of a family heirloom than a symbol of the RAF.

However, the Duchess of Cornwall did wear her RAF brooch (she is Honorary Air Commodore of RAF Halton), and Princess Anne wore a gold version of it (she's an Honorary Air Commodore of Royal Air Force Brize Norto), whilst the Duchess of Wessex wore a gold and diamond brooch (as the Honorary Air Commodore Royal Air Force Wittering).

So it's just a matter of time before Meghan is bestowed with a similar honour, especially as her husband Prince Harry has served in the military for almost a decade.
