LOL Medusa I got this from the same website, it's The Order of the Garter and all the kids have one
Just depends on what uniform your wearing or something.
Queen Elizabeth rarely gives out orders. The highest order in Britain is the Order of the Garter, and it is also the most exclusive. While the Prince of Wales is automatically a member, the Queen’s three youngest children were in their 40s before they were inducted. She never awarded the Garter to her sister, Princess Margaret, and she’s never given it to anyone that married into the family.
The Countess of Wessex received her first sash in 2010 when she was given the Royal Victorian Order (a lesser order) after ten years of marriage and several years of solid service to the Queen. She also has the Order of Saint John - again, lower in significance.
When are they worn
The easiest answer would be when the dress code says so, but that’s not helpful. So here are some ground rules:
Men wear orders with white tie in the evening and with military uniforms, as prescribed by the military guidelines for the specific uniform they happen to be wearing (for example, some uniforms may require only the star).
Women wear orders when the men are in white tie, meaning they are in gowns and tiaras (usually); they would also wear them if and when they wear military uniforms, with the same guidelines.
Extra Info
When a royal is a member of more than one order, they can mix the insignia for maximum representation. This Prince Charles pic is a great source of info:
(Still not my work)
The order of highest rank gets the prime insignia spots: the Order of the Garter is his most important order, so he wears the sash, badge and the star in the highest position on his uniform. Moving down in precedence, Scotland’s Order of the Thistle gets the second star place, and then the Order of the Bath takes the neck badge spot. His other decorations (the badge from the military Order of Merit, and various medals of commemoration) assume their regular uniform locations.
Here's Charlie to demonstrate
