Pippa Middleton will get married at her local church in Berkshire before a reception at her parents' nearby home.
The 33-year-old brunette - younger sister of Duchess Catherine - will tie the knot with fiance James Matthews at St Mark's, Engleford, in Berkshire, next May, before a reception at her parents' home in nearby Bucklebury.
A source told The Sun newspaper: "There's been a lot of speculation that Pippa would get married at her fiancé's hunting lodge in Scotland or have a massive bash in London. But she's a traditional girl and just wanted to get married at home.
"Her mum has been very involved in all the wedding planning and she wants to show off their house to all their friends.
"Plus, how can you compete with Kate who got married at Westminster Abbey and Buckingham Palace? This way, Pippa can keep it private and very personal."
Pippa will marry James next May and her famous sister - also known as Kate Middleton - is expected to be bridesmaid, while her 17-month-old niece Princess Charlotte and nephew Prince George, three, are set to be a flower girl and page boy.
Around 150 guests will be invited to the church, with more invited to the reception in a marquee at Bucklebury Manor, home of Carole and Michael Middleton.
Carole, 61, and Pippa were seen shopping for wedding invitations at a printers in mayfair this week and have also been seen shopping for wedding dresses.
