We finally stopped obsessing over the amazing custom-made tiara Michelle Dockery wears during Lady Mary Crawley's wedding to Matthew Crawley on Downton Abbey, and now there's another reason to freak!Caroline McCall, the costume designer for the British hit series, confirmed to Grazia UK that the wedding dress Dockery dons to walk down the aisle was crafted by hand, and cost 4,000 British pounds (that's nearly $6,500!) to create. "Lady Mary’s wedding dress was the most expensive costume we’ve made," McCall told Grazia. "It’s a silver lace tabard fabric that goes into a train at the back, and underneath is a silk dress with silk sleeves. The lace goes into a 'V' at the back with tiny buttons and it’s completely edged with tiny rice pearls and Swarovski crystal." A tiara made of antique diamonds and a dress edged with Swarovski crystals? No wonder Lady Mary's grandmother (played by the epic Maggie Smith) once politely asked: "What is a weekend?"
