An undated Ben Zuckerman coat- probably from the mid 1960's, in white matelassé trimmed in white fur- likely mink.  As is usual during this time period, the accessories, including the gloves and hat match perfectly.
The French word, matelassé means “quilted,” “padded,” or “cushioned,” and in usage with fabric, refers to hand quilted textiles. It is meant to mimic the style of hand-stitched Marseilles type quilts made in Provence, France. Matelassé fabric can be either hand-stitched to create the decorative features of the fabric, or woven on a jacquard loom for the appearance of quilting. Matelassé fabric is a heavy, thick textile that appears to be padded, but actually has no padding within the fabric.
