When Diana, Princess of Wales wished to send a secret message of love to Major James Hewitt, she resorted to wearing bright red nail varnish in public.

Now a young royal who’s regularly voted amongst the world’s most fashionable has sent out her own message – that is that not all blue-bloods are stuck in the past.

So just who is the young lady who was in danger of looking more goth than toff as she rubbed shoulders with the stars?

For the answer all those of us in Britain need to look across the English Channel to Europe and a royal house which has often enjoyed the ability to shock.
