Indian origin actress Kavita Kaur Sidhu is to don an ensemble worth $30 million, called "Nightingale of Kuala Lumpur", which will be the highlight of a fashion show by top Malaysian designers.
The dress is inspired by verses of 14th century Persian poet Hafiz.
"I could think of nobody else to wear it. She will unveil the dress while the poem is being read," said designer Faisol Abdullah of the fashion house Jendela KL, who unveiled a sketch of the dress to the media on Sunday.
The fashion showcase, which will feature 50 designers from Malaysia, was being organised in conjunction with the 11th Malaysian Formula One Grand Prix.
The ensemble will be on sale from April 4, New Straits Times said.
Styled from 14 metres of silk and satin batik fabric and attached with 751 pieces of diamonds weighing over 1,000 carats, the dress comes with diamond-studded shoes designed by Jimmy Choo.
The ensemble will be held together by a pear-shaped 70-carat diamond estimated around $8 million.
"For the buyer, what is more important than the value is that they are recording a time period in history with this work of art," said Nancy Yeoh, chief executive of the Stylo International Private Limited, the organiser of the show.
The show is being organised in collaboration with the Bumiputera Designers Association and the Madrid Tourism Board. It incorporates a corporate social responsibility programme, she said.
The show will feature designers from Malaysia and Spain like Tom Abang Saufi, Bill Keith, Faisol, Khoon Hooi, Melinda Looi and Albert King, with Spanish guest stars Armaya Arzuaga, Agatha Ruiz, Angel Schlesser and Maria Lafuente, specially flown in from Madrid.
