21 times Kate Middleton looked like a real-life Disney princess

Just as Cinderella did in Disney's 1950 animated film, Middleton wore a long-sleeved gown for her wedding. Sarah Burton at Alexander McQueen created the gown, which is estimated to have cost $303,444, or £250,000.

She also wore a diamond tiara that made her look even more regal.

She wore the lavender-pink gown, which was designed by Jenny Packham and covered in Swarovski crystals, while attending a charity event for Absolute Return for Kids, also known as ARK.

Her gown had both a white diamond belt and a flowing skirt. Middleton wore the simple dress and a matching diamond bracelet to the BAFTA Brits to Watch event, held at the Belasco Theater in Los Angeles.

Middleton wore a short-sleeve dress with lace accents for the event, as well as a jeweled belt and a flowing skirt. Her classic gown was a bold shade of teal, similar to the blue-green color worn by Jasmine throughout "Aladdin."

Middleton wore the dress while at the Royal Albert Hall for the British Olympic Team GB gala.

Middleton wore the short-sleeve red dress, which had a satin belt around the waist, while meeting with Chinese President Xi Jinping in the ballroom at Buckingham Palace.

To complete the princess look, she wore a diamond tiara and sparkling bracelets on both wrists.

Her dress featured sheer sleeves wrapped over a halter-style top and a sparkling belt atop her skirt. The pale-blue color of her ensemble was nearly identical to that of Cinderella's ball gown.

Middleton wore the blue ensemble, which had a beaded top and floor-length skirt, while attending the Gala Bollywood Dinner at the Taj Palace Hotel in Mumbai, India.

She also carried a sparkling handbag throughout the night.

While Elsa from "Frozen" is known for wearing a sparkling-blue dress and sheer cape, Middleton put her own twist on the style by wearing a fitted royal-blue dress.

The dress also featured small cutouts across the shoulders.

The off-white dress featured statement jewel embellishments, while its cape-style overlay added a royal touch.

Middleton wore the dress while attending a dinner hosted by King Harald V of Norway.

This time, however, she seemed more inspired by the color and fabric of Elsa's dress than its overall style.

While attending the Royal Variety Performance in London, Middleton stepped out in a powder-blue gown that was covered with a jeweled overlay. Her long sleeves were nearly sheer, and the bottom of her dress revealed sparkling heels.

Just like the classic Disney princess, the duchess wore a baby-blue dress with short sleeves to a royal event. Unlike Cinderella's gown, however, Middleton's dress had ruched fabric and a mermaid-style skirt.

She also donned a diamond tiara, which previously belonged to Princess Diana, and a statement necklace that added extra flair.

She resembled Cinderella once again while at the Queen's Annual Diplomatic Reception.

The duchess wore a pale-blue gown, designed by Jenny Packham, which was encrusted with jewels and layered with sheer fabric. To complete her regal ensemble, Middleton wore another dazzling crown, called Queen Mary's Lover's Knot, that was once owned by Princess Diana.

Her floor-length Alexander McQueen gown featured floral detailing across her left shoulder.

She completed her ensemble, which resembled that of a Disney bride, with a diamond bracelet, white clutch, and pearl earrings.

In her multicolored Gucci gown, Middleton looked as if she were channeling Aurora from "Sleeping Beauty" or Giselle, the princess from Disney's 2007 film "Enchanted." She added ruby earrings, a maroon belt, and a velvet clutch for an extra touch of glamour.

She wore the ensemble at the 100 Women in Finance Gala in London.

She wore the light-green ensemble, which had long sleeves and an ankle-length skirt, with nude heels and a matching purse.

The color, sparkly fabric, and puffy sleeves made her dress look like something princess Tiana would wear.

Middleton may not have red hair or a Scottish accent, but she has nailed Merida's style. She wore a green dress, similar to the one worn by Merida in the 2012 film, while at the opening of the Centre of Excellence in London.

She looked sophisticated and chic in the ensemble, which she paired with nude pumps, a thin handbag, and delicate jewelry.

The British royal basically skipped the princess stage and looked like a reigning queen in a ruffled white gown designed by Alexander McQueen. Her dress also had capped sleeves and a sweetheart neckline.

Once again, Middleton accessorized with the Queen Mary's Lover's Knot tiara. She also debuted a red, white, and blue sash, which is said to have been a gift from the Queen.

She attended the racing event wearing a gray-blue, polka-dot dress with sheer sleeves, a bow collar, and lace detailing. Paired with a matching hat, the dress made her resemble one of Disney's most beloved characters: Mary Poppins.

Her white-and-gold Alexander McQueen gown was one that she previously wore in 2012.
