Why are princes Charles, Harry, and William always wearing military uniforms even though they're obviously not on any kind of active duty? ~

Dress uniforms look cool, and given how royalty historically were the only people who had enough resources to make proper armor and a sword to begin with, it makes sense that they'd be keen on keeping that tradition. Plus, the Royals seem to have some history of military service.

All that said, Prince Andrew can fuck right off with this "I demand to be an admiral at the funeral!" mess.

Point was they did. Most of the males in the royal family served in the military. King George VI served as an officer on a battleship during WW1. Known as the pseudonym Mr. Johnson, he actually saw action in the Battle of Jutland.

I don’t think Prince Henry any more

It's a fetish of the Royal Family to dress up like that.

It's a ceremonial thing. PoW is an honourary 5 Star ranker of all three RAF branches

I think its a custom for those who served to wear a uniform at certain events.

Ceremonial/ tradition🙂

1. It has always been traditional for all royals to do this for centuries.
2. They all did required military service but unlike your average joe blow from the streets they still represent their country each and every time they are in public.
3. Most male royals hold rank in some branch of the military or have an honorary title.
Even average people often wear their military uniform to their wedding or some such extremely important event.

Because they are fashionable
