Like all couples getting ready to tie the knot, Pippa Middleton and her husband James Matthews had some very specific requests for their wedding day.
From saying yes to the perfect dress to finalising the menu and narrowing down the guest list, there's a lot to consider when planning a wedding.
But the Duchess of Cambridge's younger sister had a slightly unusual idea when it came to the seating plan.
Pippa married James Matthew in a stunning ceremony on May 20, 2017, at St Mark's Church in Englefield with their nephew Prince George and niece Princess Charlotte as the pageboy and bridesmaid.
Following the ceremony, the 300 guests made their way to Bucklebury Village Hall, where they parked their cars ahead of the evening celebrations.
They were then driven to Pippa's parents' estate - but not before each guest had their photo ID checked and their own password to get in.

When they arrived, they were greeted by a 140ft glass marquee in the garden, which had been decorated in an enchanted forest theme.
Guests took part in a number of fun games and watched an excellent light show before they were served food and drink including mini haggis, deer carpaccio, langoustine claws and asparagus with Hollandaise sauce.
But when it was time to sit down to eat, guests were surprised to discover that Pippa hadn't followed a conventional seating plan chart.
Instead, she set a rule that they weren't allowed to sit with their other halves.
Although this is quite unusual, it does allow guests to get to know each other.
According to Harpers Bazaar, the etiquette guide Debretts, "It is up to the host to decide whether husbands and wives are to be seated together or apart at formal events."
This meant that despite travelling 3,000 miles across the pond, Meghan Markle wasn't allowed to sit with Prince Harry.
But, it turns out that Meghan almost didn't get an invite at all.
Meghan and Harry hadn't been together for too long when Pippa and James got married, so there was a lot of media attention on them.
This worried Pippa as she feared that it would "overshadow" her big day.
In their book Finding Freedom, authors Omid Scobie and Carolyn Durand, claim that Meghan had planned to attend the full day, and even bought her outfit, but the decision was made that she skip it.
So Harry went to the ceremony by himself, leaving Meghan at another wedding guest's Airbnb before they met up later to go to the reception together.
