Boaters are often worn higher on head due to shallow crown height or at can be worn a slanted angle. Likewise Berets are worn higher ( some say 2 finger above eyebrow - though depends on ones fingers size!). The diagram show this cross section of the head is smaller than the standard "hat" position. So as a rule a Beret or Boater is one size SMALLER than standard HAT size as heads tend to taper in further up to smaller a cross-section. #millinery #judithm #hats
