The train of the wedding dress is festooned with 7,000 Swarovski crystals and the dress was completed in 70 days. The gown has been designed by Romanian designer Ioana Comanescu of the “Il Creatore” bridal shop. Priced at GBP 3,500 (US $5,135), the wedding gown with the longest train will be sold at the wedding fair through an auction. The previous record was held by a wedding dress (4,468 ft) designed by Andreas Evstratiou in Cyprus.
