To celebrate turning 21, Princess Olympia of Greece threw a party for the royal history books. Teaming up with her father Pavlos, Crown Prince of Greece — who turned 50 in May — the pair hosted a giant bash on a sprawling estate in the English countryside.

Set in the vast garden as well as inside, the dreamy location called for some equally lust-worthy dresses.

Socialites, celebrities, and other and well-known fashion faces all attended, sticking to Olympia’s dress code calling guests to revolutionize a traditional black tie look.

The birthday girl wore an embellished bodysuit and tulle skirt by Steven Khalil, pairing the revealing ensemble with rainbow-striped Gucci platform trainers.

Paris Hilton and sister Nicky Rothschild also turned up in glitzy gowns while Poppy Delevingne opted for a tulle Marchesa design.

The late Princess Diana’s close friend India Hicks went for a truly show-stopping look, painting a tuxedo onto her body.

If it wasn’t the fashion that caught everyone’s attention, it was definitely the dessert table which was piled high with lots of treats including macarons and profiteroles along with Olympia’s enormous birthday cake.
