Heather Mills is reported to have ordered £10,000 (€16,000) worth of Chantilly lace for her wedding dress.
The former model will use the French fabric to create an off-white lace and silk dress.
She is planning to marry Paul McCartney at a secret venue later this year.
A spokeswoman for lace company Solstiss Bucol confirmed that Heather has ordered the lace to McCartney's New York office.
It is thought that Heather will opt for a traditional dress, with a corset-style bodice, veil and train.
