Thank you Steve! Here is a Dobbs boater using a sewn braid construction of soft straw. It is very flexible, with the brim shape held by the use of an unusual rolled edge. I've not seen another like it. It can be dated quite reliably to the 1920s from the Dobbs store location ephemera collected by Brad Bowers. I selected this hat to wear to my daughter's wedding three years ago - perhaps not the perfect choice but it is very comfortable and I was encouraged by knowing that no one would be looking at me.
