Earlier this week I posted about
Elsa Schiaparelli and her use of plastic zippers in the 30s. Here is another example from her Fall/Winter line from 1935/36. The dress on the left is a black wool knit lined in white satin. The bodice of the dress has a white plastic zipper at the front. Schiaparelli used the same zippers to decorate the gloves. Love that belt with the angled buckle!
