Nancy Shevell wedding dress inspired by Wallis Simpson outfit.

Nancy Shevell’s wedding dress, designed by Stella McCartney, was a “remake” of the 1937 Wallis Simpson wedding outfit.

Stella McCartney, the fashion designer daughter of Sir Paul, created the wedding dress for her step mother, Nancy Shevell, being inspired by the gown worn by Wallis Simpson for her marriage to the Duke of Windsor in 1937.

The confirmation of the wedding dress’ style influence came from presenter Barbara Walters, who is Nancy Shevell‘s second cousin, on an episode of The View.

Barbara Walters said: “Stella re-did it for her.”

The major influence of the Wallis Simpson gown was reflected on Nancy Shevell’s upper part of her wedding dress, which had the same delicate buttoning and nipped-in waist. Stella McCartney creation has been modernized with a knee-length hemline and v-neckline.

Another difference between Nancy Shevell’s outfit and Wallis Simpson’s Mainbocher crepe gown was the color, which had not been white but a light shade of “Wallis blue” – said to match her eyes.

Wallis Simpson wedding dress, which was given to the Metropolitan Museum in New York 1950, went on to be one of the most copied dresses of all time.

Barbara Walters also revealed Nancy Shevell wore three outfits for the Sunday wedding.

Nancy Shevell also wore “a long, beautiful sort of plum-color chiffon dress” for her wedding reception at Paul McCartney’s North London home and then later “went upstairs and and (they) put on jeans and T-shirts”.

Nancy Shevell married Paul McCartney on Sunday at Marylebone Register Office in central London, where he married Linda Eastman in March 1969.

The 51-year-old American millionairess is the third wife of Sir Paul McCartney. She started dating the former Beatle in November 2007 and it was announced on 6 May 2011 that the two had become engaged.

Nancy Shevell and Linda McCartney, Paul’s first wife, were pals. She was diagnosed with breast cancer in her 30s, around the time Linda was losing her battle. The two women became then close friends.

Nancy Shevell is a breast cancer survivor. Nancy and her ex-husband Bruce Blakeman knew Paul McCartney, his wife Linda and the children when they visited the Hamptons where Linda had family.

Nancy Shevell and Paul McCartney have a combined fortune of over $1 billion.
