Elizabeth and David Emanuel catapulted to fashion stardom when they designed Princess Diana's royal wedding dress in 1981, but earlier the same year, they created another gown that put Lady Diana Spencer on the map. When Lady Diana Spencer made her first official appearance with her future husband, Prince Charles, she turned to the then-husband/wife team of the Emanuels to design a show-stopping evening dress, but it turns out a second black silk taffeta gown was created from the same material.
The shimmery ruffle-trimmed gown, known as the "Sister Dress," is now up for auction in the Julien's Auctions's Princess Diana's Style & A Royal Collection event. More than 300 pieces of royal fashion and memorabilia will be up for sale, including Diana's iconic "Caring Dress" and a rare letter she wrote to a footman at Buckingham Palace.
