Romanian designer Oana Comanescu has created the world’s longest wedding dress, successfully making it into the Guinness Book of Records.

The train of the gown measures 1,579 meters and is studded with as many as 7,000 Swarovski crystals. It took 25 expert tailors to make it.

“We’ve succeeded in putting Romania in the Guinness Book of Records once more,” said Comanescu.

The dress, which cost more than $4,000 to put together, is displayed at the E-Marriage Festival in Bucharest.
