Deborah Vivian Marquit (born in 1954 in Brooklyn, New York) is a fashion designer, specializing in women's couture and lingerie. Marquit is the first known fashion designer to introduce the use of fluorescent (neon) colors in the creation of women's foundation garments (bras and underwear). In 1984, Marquit pioneered the concept of high-fashion in lingerie disrupting traditional ideas around undergarments. This innovation earned her first sale to seventeen Bloomingdale's stores across the United States that launched her brand globally. Beginning in 1985, Marquit introduces fashion fabrics to intimate apparel to add to her vision of conceptual bras and underwear made with atypical fabrics, in camouflage print, pleather and denim, initiating the idea of wearing lingerie as clothing.
