According to People, a giant, palace-like marquee (aka an ornate, glass tent!) has already been set up on the sprawling, 18-acre grounds at the Middleton’s home.

The expansive structure was reportedly shipped from Belgium and was installed by Peppers Marquees, a company that has worked with Prince Charles for years.

The best part of the marquee is for sure the luxury toilets, which Pippa is reportedly referring to as the “throne room!” The bathrooms allegedly include individual, wooden cubicles, spot lighting, large mirrors, and vanity units — how fancy!

Around 300 guests are expected to attend Pippa’s lavish wedding, including Prince Harry’s girlfriend, actress Meghan Markle. The author’s royal niece and nephew, Princess Charlotte, 2, and Prince George, 3, will reportedly serve as a bridesmaid and page boy during the ceremony.

Though Kate will be in attendance at the wedding, she will not have a special role in Pippa’s bridal party as to “not upstage her sister.” As for Pippa’s wedding dress? A royal style expert recently revealed the bride could wear something “lavish and romantic by Marchesa or upmarket luxe by Ralph & Russo.”

“Other possibilities include Temperley, which both she and Kate wear regularly or Jenny Packham,” the style expert said, adding, “[Whatever the design], the dress will look as good from the back as the front!”

James, 41, previously popped the question to Pippa in July 2016. The couple reportedly first began dating less than one year before their engagement following the author’s October 2015 split from longtime boyfriend Nico Jackson.
