After working with the well-known fashion designer Roy Halston in the 1970s, Karen Bjornson not only became one of the most famous “Halsonettes,” but she also became Halston’s primary source of inspiration. This was a double honor for Bjornson. Because of this, Bjornson became Halston’s most significant source of inspiration.
Modeling for various high-end fashion designers, such as Donna Karan and Ralph Lauren, was one of the responsibilities that came with Bjornson’s position as a fashion model. Bjornson returned to the fashion industry when she turned fifty years old, after having taken a hiatus in 1989 to concentrate on raising her two daughters. Prior to this, she had worked in the fashion industry when she was younger.
