From 1961- a Ben Zuckerman coat and dress ensemble in pink cotton pique. This outfit would be perfect for spring- you could wear the coat when it is colder and remove it as the weather improves.
Piqué, or marcella, refers to a weaving style, normally used with cotton yarn, which is characterized by raised parallel cords or fine ribbing. Twilled cotton and corded cotton are close relatives.
