Socialite Kim Kardashian reportedly wants a wedding dress similar to the one worn by Duchess Catherine when she walked down the aisle in 2011.

The British royal wore an Alexander McQueen gown designed by Sarah Burton for her D-day.

"Kim is absolutely obsessed with everything Kate and William do. She considers her own family 'American Royalty'. Kim loves Kate's style and while she is planning on several gowns for her big day, she wants the one for the ceremony to look something like Kate's dress," a source told Grazia magazine.

Kardashian and her rapper-fiance Kayne West, who have six-month-old daughter North together, are planning to sit on golden thrones during their reception. They believe it will tie in nicely with the royal-themed home they share in California.

"They think it would be really cool to have gold thrones to sit on during the reception. They have already got a Buckingham Palace-themed room in their new home, which they are using as inspiration," said the source.
