Pippa Middleton and James Matthews have reportedly set a date for their big day. Kate Middleton's sister and the 41-year-old hedge-fund manager, who got engaged on 17 July, will tie the knot in 2017.

According to Daily Mail, the 33-year-old English socialite has made "luxurious 'Save the Date' invitations" which is to be sent to her friends and family inside their Christmas cards. Adding on, Pippa's wedding dress is allegedly worth £10,000.

The Duchess of Cambridge's younger sister shot to fame when she wore a tight-fitting dress at Kate and Prince William's fairy tale wedding in 2011. Pippa is hoping her wedding dress will outdo the dress she wore to her sister's wedding.

David Emanuel, who designed Princess Diana's wedding dress, suggested that Pippa should avoid a wedding dress like that worn by Kate. He told to Mail Online: "I personally, would put her in something very soft, perhaps chiffon, with a train of course because it's dramatic. Possibly a little lace bodice, soft and fluid, I mean she's got a great shape."

"And I would say the complete opposite of Kate just so she makes her own statement really. Soft and pretty," he added.

Pippa and Matthews had first dated in 2012 but split the same year. In August 2015, the duo sparked rumours that they are dating again after he was spotted at Pippa's side during a Middleton family vacation at his parents' hotel. They have been together this time for less than a year.
