Miss Wales Amy Guy has jetted off to China hoping to be crowned the most beautiful woman in the world.
The dress is guaranteed to turrn heads
And she packed an extra-special good luck charm - a replica of the dress worn to the Oscars by Hollywood star Charlize Theron when she picked up the best actress award.
The ivory gown was donated by a London fashion firm to wish her good luck.
She said she hoped it would bring her as much luck as it did the Monster star.
Amy, 21, from Ruabon, Wrexham, will wear the dress - which is covered in sequins, has a plunging neckline, and is split to the thigh - on the night of the judging.
Before leaving the UK on Sunday, she said: "I'm so excited! The dress is fabulous - it's everything I could want.
"I hope it brings me as much luck as it did Charlize.
"Winning Miss World is my dream come true - and hopefully I'll look as good as Charlize to wow the judges on the night.
"The dress is so gorgeous and elegant - with a little bit of sex appeal - it's sure to do me well."
Amy - who is training to be an architect - has vowed to keep her feet on the ground and has spent the past week looking for a job.
She said: "It's been really hectic but I've had a couple of interviews for architects jobs.
"I'm determined to keep my life as normal as possible even with all the excitement of Miss World."
Amy Guy will be carrying Welsh hopes
The new system of voting in the 4 December Miss World contest means viewers from all over the world can use their mobile phones to text in their votes.
And Amy's hoping everyone in Wales will be sending text messages, voting her the winner.
She added: "We're only a small country and I'm up against girls from America and China, so everyone's got to support me.
"I'd love to win and be able to make Wales proud."
Amy was crowned Miss Wales at a beauty contest in Swansea in September.
There was a cameo appearance by Helen Morgan, who was Miss World for just four days in 1974.
