It could possibly be one of the most perfect dresses for bridesmaids and brides ever made, and Leighton Meester decided to run up a New York street in it.

Of course, this was just for her role as Blair Waldorf in US smash-hit teen drama Gossip Girl. The wedding dress, believed to be made by Chinese-American designer Vera Wang, is one of perfect elegance.

Far from the Kate Middleton-esque lace sleeves, this dress is long, flowing and frothy. Leighton looked like a Disney princess in this dress, which is strapless with an embroidered bustle.

In the series, Leighton's character is set to be married to a French prince, but in true TV style something goes terribly wrong and she is left fleeing the church into a waiting car.

The shows' executive producer Josh Safran has promised fans that the wedding is going to be "big and lavish and twisty and juicy", so no doubt you will be able to Leighton rock this sumptuous dress when the episode airs in the UK.
