Neopolitana Ice Cream Hat

A classic hat for a formal event is trimmed with a wide petersham ribbon bow. It's made from fine straw in two colours and a silk band in ivory, so could be worn with any of the three tones.

The difference between petersham and gross grain is that petersham has a wavy edge and gross grain a straight edge. Milliners use petersham to sew into the brim of hats sewing every third ridge, this creates the band that is worn close to the forehead.
