The Most Beautiful Royal Gowns, Ranked

The British Royal Family must abide by a list of centuries-old rules and protocols, and that extends to their fashion choices.

That’s right — the Royals have a dress code. Take a look at our ranking of some of the most beautiful royal gowns.

Princess Diana in Catherine Walker

Bella Hadid may be best known for being Gigi Hadid's sister, but she's a supermodel in her own right and shows it here!

Duchess Catherine in Jenny Packham

Spanish actress Penelope Cruz is known for her smoldering good looks, and we see that she's fully ready for this special occasion in this amazing and classy gown.

Spotted on the red carpet with her date, costar in Asghar Farhadi's film, and real-life boyfriend, Javier Bardem, she is a total head turner in this gorgeous black dress.

We love the gradient theme of this dress, which keeps from getting too dark by incorporating different shades of grey and black.

Princess Anne in Floral Ruffles

Actress Julianne Moore is a truly timeless beauty and is known for her trademark stunning red hair. Here, she plays up her best asset to the max by rocking an equally red gown by Givenchy.

The daring dress featured two super-high splits, but Julianne looked absolutely fabulous in the frock.

She matched the dress with a blinged-out statement piece by iconic jewelry designer Chopard and kept things classic with a pair of simple, classy plain black sandaled heels.

Princess Diana in Hachi

British actress Cate Blanchett is known for always being a class act, and her stunning Cannes 2018 red carpet look was no exception to the rule.

She kept her blonde tresses swept back in a simple bun, which kept attention focused on her amazing gown.

The dress featured angel sleeves which split perfectly to show off her toned arms. The ornate black lacework was coupled with a beautiful sheer fabric.

Dramatic dangling statement earrings rounded out the exceptionally glamorous look.
