Britain's Duchess of Cambridge has reportedly bought Prince Harry a Grow Your Own Girlfriend' kit for Christmas.

Kate Middleton married Prince WilliamPrince William in April and is celebrating her first festive season as part of the royal family.

It's been decided that the group will give each other low-key but fun gifts this year, in part due to the on-going global financial crisis.

While Kate has chosen something sentimental for William's grandmother Queen Elizabeth II, she's embraced the joke theme when it comes to his single brother Harry.

"Kate and William have bought him a Grow Your Own Girlfriend kit, along with a more stylish gift Gucci loafers because all his shoes have holes in them,'" reports the British edition of Grazia magazine.

The duchess has opted for a framed photograph of the queen with her beloved pet corgis for the monarch, while William will be getting pictures of their recent trip to Canada and a beanie hat.

The young couple will spend Christmas at the royal family's Sandringham Estate in Norfolk.

Christmas Eve will be an "informal" affair, with soup, cheese and port on the menu. December 25 will start with breakfast at 8.30am, followed by a church service.

After that dinner will be served.

"The queen is in charge of the seating plan," Majesty magazine editor Ingrid Seward explained. "As the newcomer Kate is likely to be placed next to Prince Phillip. She's probably have Prince Harry on her other side, to provide some light relief."

During the feast of lobster, turkey and Christmas pudding the family will pull crackers, which have been made by Kate and her mother-in-law Camilla, Duchess of Cornwall.
