Diane Gilman net worth: Diane Gilman is an American fashion designer and entrepreneur with an estimated net worth of $5 million dollars. Born in Beverly Hills, California, Diane Gilman spent much of the 1960s making custom denim pants and jackets for rock stars. She then moved on to her own washable silk line, with a shop based in New York. She lost her line to a Chinese company that swindled her out of the rights in the 70s. Fast forward to 2012, and she is now one of the Home Shopping Network's most popular sellers. She designs jeans, tops, shorts, and dresses with "baby boomer" women in mind. Her jeans have become especially popular, and multiple major high-end retailers, such as Bergdorf-Goodman, have approached her with an eye to carrying her line. However, she continues to do most of her business via the Home Shopping Network, and has mentioned in multiple interviews, that though she is not famous in design circles, the Home Shopping Network is the place where she feels most comfortable.
