Tom and Lotty

Only the bravest brides would let their groom organise the biggest day of their life, by himself. The grooms get 12,000 pounds and the brides get no say in how it is spent. With a million ways to splash the cash and a million things to organise, can the guys pull it off in just three weeks? And will it be for better or worse?

The pressure is on Bristolian brickie Tom (28) to create a showstopper of a wedding for his bride Lotty (30).

They have been together for four and a half years, but because Lotty has never had the chance to celebrate her 18th or 21st birthdays, after her mother died of cancer, her wedding day means everything to her.

So will Tom's ambitious vision to get married in a Mongolian yurt be what Lotty is really hoping for? And will fashionista Tom get carried away with style over sparkle when it comes to picking out Lotty's all-important wedding dress?
