Trimmings varied according to the changing styles and whims of the individual wearer, but most bonnets of the period followed some general rules with regards to form. Rows of gathered net lining the brim was a fashion carry-over from the decade before, and a decorative curtain (also referred to as a "bavolet") appeared on most bonnets in order to shade the wearer's neck and accommodate for the low hairstyles. Another standard of 1860s bonnets is bonnet ties. There were often two sets, a thin pair of "utility ties" to take the strain of tying the bonnet, and another set of wide ties of silk or another fancy material. These rich ties were tied below the chin in a bow or left untied to show off the beautiful print or material.
