Hunt  began by designing children's clothes and selling them to a department store called Haggerty's. The first label was called Fairy Frocks, a line for toddlers, which was then later changed to Jean Carol.  Jean was short for Jeanette, her daughter, and Carol for herself -  Carolyn Margaret Hunt (Peggy was her nickname). Under the Jean Carol label Hunt made dresses for many Hollywood stars, including, Marlene Dietrich, Bette Davis,  and Mary Pickford.

She also developed the Collegienne department at Bullocks Wilshire, a luxury department store in Los Angeles.  Under the Peggy Hunt label, her speciality was evening and cocktail dresses,  very much in the tradition of Hollywood glamour.  As such, the dresses were very popular with actresses such as Lucille Ball and Anne Miller.

Thanks to Peggy Hunt's granddaughterdaughter, Jacqui Hyland, for this information.
