The supermodel is taking her role as a representative for the French lingerie brand seriously.
To promote the launch of the new ad campaign Seymour was photographed by Peter Lindbergh. The 39-year-old beauty met with New York consumers and stressed the importance of finding the best fit in lingerie.
"Put the right undergarment on and you are transformed," said Seymour, adding that women are more and more seductive with age because they wear effective bras that hold their shape.
"Today we can have all of that but in something that is soft, modern and comfortable," she concluded.
