Kate wore "something blue" to a friend's nuptials at St. Peter and St. Paul's church in Northleach, Gloucestershire in 2010. She paired a cobalt knee-length flowy frock by Issa with a fitted black blazer. Blue is Kate's color of choice—when Vogue UK analyzed 100 outfits worn by Kate from April 2011 to now, they determined that she's worn the color 24 percent of the time she attends events.
