This smart grey trilby I purchased in a hat shop in Whitby.
What is the difference between a fedora & trilby, its dam confused out there even the experts contradict each other.
From what I can see its basically comes down to the size of the brim, big brim (3" or more ) Fedora, small brim (less than 3") Trilby, although you will find many hats that cross the 3" border both ways.
This hat has a gutter down the crown, a pinched front and kettle curl around the brim
