Unless you happen to be a celebrity or royalty, it's unlikely you can top Princess Olympia from Greece's 21st birthday party, which took place on Sunday.
For starters, it all went down on a vast estate in the English countryside, like an effing fairy tale. Just look at this house! (The balloons and flowers weren't so bad, either.)
Pretty much everyone there was dressed to the nines, and then some—after all, the invitation said to "Revolutionize Your Black Tie," according to photos that guests posted to Instagram. Meanwhile, Olympia slayed in a neutral bodysuit with a peekaboo skirt, which she paired with a chic AF fascinator and rainbow-and-gold platform sneakers—because why not?!
Paris Hilton was there, as was her sister, Nicky, wearing quite the Marie Antoinette getup. Revolutionary, indeed!
Meanwhile, Poppy Delevingne wore this gorgeous ombre Marchesa creation.
Her dad also attended in style, wearing a pink blazer.
Then someone showed up in a painted-on tuxedo shirt, and I won't even pretend to understand how to pull that off.
Are you getting the hint that this guest list was out of control? Valentino Garavani, a.k.a. THE Valentino, was there too, in case you were wondering.
And so did these amazing head pieces. FYI, that's the crown princess of Greece wearing the stars.
Happy birthday, Olympia! I'll just be over here waiting for my invitation to next year's shindig.
