How do I learn to carry myself like a stuck-up proper British Royal?

I love the Royals! I love the power, sexy looks, money, and arrogant haughty attitudes. I try to walk around with my head held high like I am a Royal and I do feel like a Royal inside. I have lost a few friends who say they don't like my attitude and that's fine, because inside I really feel like a Royal. How can I carry myself more like a Royal?
