It took guests more than three hours to roll out the gown of Lin Rong, a Chinese bride who recently broke into the Guinness Book of World Records by wearing the world's longest wedding dress. Costing almost $6,000 and complete with 9,999 silk red roses attached to it, Lin's dress measures in at 2 km (1.2 miles) and was completely handmade by her groom's family. The former old record was set in Romania with a dress that was recorded at 1.5 km long.
