1885 Poke Bonnet Poke bonnets were popular in the late 18th to mid 19th century and are characterized by a flat crown and deep, projecting brim only in the front. The wide silk ribbon was likely only decorative and not used as a closure. There are remnants of an elastic strap stitched in to the hat lining. This elastic strap was encased in fabric and would have been worn under the chin, securing the hat on the wearers head. It was likely worn for formal afternoon events.
