Kate Middleton vintage Amanda Wakeley April 2011.jpgWith less than three weeks until the royal wedding, the latest rumour to do the rounds is that Kate Middleton has commissioned not one, but three wedding dresses to choose from on the big day. The three gowns have been ordered from three different designers so there are two "back ups" in case anything happens, such as the designer of her chosen dress somehow gets leaked.

This may seem extreme at first, but after the wedding guest list was recently leaked, it is kind of understandable. And apparently it is not uncommon - Princess Diana enlisted Emanuel to create two wedding gowns - one to wear and the other a replica in case anything should happen to the original.

According to Fashionetc.com one of the designers brought on board is Jasper Conran, but insiders are still hitching their bets to Alexander McQueen's Sarah Burton. Cathy Horyn seems adamant on Burton's involvement, after British Vogue editor Alexandra Shulman, reportedly suggested that Middleton wear McQueen.

Bets are still on Burton to take out the honour, with bookmakers also placing odds on Bruce Oldfield, Alice Temperley, and Issa's Daniella Helayel.

"What is increasingly clear as the Big Day approaches is that Oldfield, Helayel, Temperley and the design team at Catherine Walker are all involved with the wedding in some way," reports WWD.

Meanwhile the Princess-to-be was spotted out and about yesterday on her last formal engagement until the wedding (pictured). She and Prince William visited the Darwen Aldridge Community Academy in Lancashire in matching navy outfits. Kate appeared very polished and royal-like in a blue vintage Amanda Wakeley suit, which she teamed with a clutch, flesh-coloured tights, and a pair of similar blue LK Bennett court shoes.

In this ensemble, and with her hair half up she reminded me somewhat Princess Mary of Denmark. Do you agree? What do you think of her latest look? Tell us by leaving your comments below.
