The Guinness Book of World Records recognised the item on the silk and lace gown as the longest train, beating the previous record held by a Dutch designer.
Pedestrians, however, didn’t seem to make much of the event, organised by gown’s creators: the Andree Salon fashion house and the organisers of this year’s biannual Wedding Fair in Bucharest.
A few bystanders looked up at the balloon, but many others ignored it.
The train, which took 100 days to stitch, was crafted by a team of 10 seamstresses, said salon spokeswoman Lavinia Lascae.
4,700 metres of taffeta, 5.5 metres of Chantilly lace, 45 metres of lining, 1,857 sewing needles and 150 spool threads were used in the creation of the gown and train.
The lace was imported from France, while the taffeta and other fabrics were purchased from Italy, costing approximately £5,000, she added.
Beating a Dutch designer to the record had an added dimension for Romanians, as many are still angry after the Netherlands opposed its entry into the European Union’s visa-free travel zone.
Dutch Prime Minister Mark Rutte recently demanded that Romania and Bulgaria do more to reform their justice systems and combat corruption and organised crime before he supported integration.
“If the Netherlands does not allow us into Europe, we’ll take them out of the world records book,” said Alin Caraman, an organizer of the Wedding Fair.
In 2009, a Chinese bride famously got married in a 1.4mile-long wedding dress that took more than 200 guests over three hours to unroll.
The previous record for the world’s longest train stood at 2,488 metres.
