Royal weddings are fun and all, but for anyone who's not that interested in the royal family and more interested in what the royal family's nearest and dearest wear, Princess Eugenie's wedding was everything and more. One standout? That would be model-turned-actress Cara Delevingne. Who could forget her top hat and tails? Well, even the most daring models have second thoughts, it seems. According to Cosmopolitan, Delevingne asked permission before breaking royal protocol.

"Eugenie has been a friend of mine since I was a kid and I've always wanted to wear tails," Delevingne told The Daily Mail. "I texted her, as I wasn't sure about it and she was like: 'Of course, I expected nothing else from you!'"

Eugenie's dress code was one of the most stringent, ever. Compared to Prince Harry and Meghan Markle's decidedly laid-back ceremony, which allowed male guests to wear suits, Eugenie's called specifically for morning coats. Her invitations clearly stated that female guests were to wear "day dress and a hat." Delevingne didn't, opting instead for a menswear-inspired tailored tux that included all the trappings of formal attire: a cummerbund, a tie, and a top hat.

Clearly, it pays to be chummy with the bride. Otherwise, we wouldn't have been treated to the sartorial splendor of Delevingne's ensemble.
