Garment bags were spotted being delivered to 33-year-old Middleton’s London home, leaving many to speculate if the bags could contain her wedding dress.
The reception will take place at her parent's home in the English countryside, where a giant glass enclosure has been constructed for the 300 guests expected to attend the reception.
Only 100 will attend the ceremony that will take place at St. Mark's Church, which was being spruced up for Middleton and Matthews' big day.
Middleton and Matthews have been engaged since July 2016, when the 41-year-old hedge fund manager proposed during a trip to the Lake District.
Her sister and Prince William's adorable children- George and Charlotte- are both in the wedding party. George will be a page boy and Charlotte a bridesmaid.
