‘Circular saw’ of the 1920s

From ‘Gentleman’ (2010). Bernhard Roeztel on that handsome & uncomfortable siren of summer, the straw boater.

The black band is rather sober, however you need to keep in mind that a century ago black was the universal colour of businesswear and the circular saw was habitually worn with a suit of that colour.

Today such a hat might carry rather a charcoal or navy band. Unlike a panama though, a genuine ‘Strat’ is heavy, rigid & grates on the scalp. Best worn with an excellent sense of balance & a padded inner headband.
