This is a picture of Peggy O'Neill who was a fit model for Ben Zuckerman throughout his career.

She is wearing a dress designed by Ben Zuckerman, and looks fantastic.

Fit models are women who had perfect figures- their busts, waists, hip mesurements corresponded exactly to the industry sizing- usually around a current size 6. Fit models are integral to the design process- they confirm to the designer how the design will look on a real person.
