Names that have already been touted in connection with the fashion commission of the century include Bruce Oldfield – one of Princess Diana's favourites. Kate's mum Carole and her sister Pippa were spotted at one of his London boutiques in January.
Sarah Burton, director of Alexander McQueen (below), has also been mentioned. She is said to have caught Kate's eye for the dress she created for the wedding of Sarah Buys to Camilla's son Tom Parker Bowles (below left).
Now fashion writer Anne Chertoff has claimed on her blog that Jasper Conran (above), another favourite of the Princess of Wales, has also been asked.
The British designer was responsible for the wedding gown of Princess Margaret's daughter Lady Sarah Chatto (above left).
Earlier this year, he said he would be delighted to design the future Princess' wedding day outfit, saying he would make her "a very vision of England".
Fashion writer Anne writes: "FashionEtc has learned that Jasper Conran may have landed the plum assignment; however, he is not alone.
"Sources tell us that Middleton has commissioned three wedding dresses from three different designers.
"She has two backups should the designer of her chosen wedding dress be correctly leaked."
Jasper Conran's spokesman said: "If he has been asked to do it, it's news to me."
William's late mother announced the designer of her dress, Emanuel, well ahead of her wedding, but had two dresses made so she had a backup plan, should her first choice be discovered.
A spokesman for St James' Palace declined to comment, saying: "Miss Middleton is keen to keep one secret for the wedding day itself. "
Whether the stories are true, or even just a fabrication to keep the world guessing remains to be seen.
If Kate gets her way, royal fans and the press alike will have to wait until April 29 to find out one way or another.
