This is a rare mid century Iris lingerie nightgown designed by Sylvia Pedlar. This fine white cotton gown was purchased at B. Altman. Many credit Mrs. Pedlar for inventing the babydoll nightie. This one is really beautiful and has exquisite lace and embroidery. This is labeled a size small and 38" from the top of the shoulders. It is meant to be over sized and is in excellent condition. You can see many of Sylvia Pedlar's lingerie pieces in the Metropolitan Museum of Art Costume Institute.
