I don't believe there is such a thing as a bespoke hat where as with suits and shoes unique patterns and lasts are made of the individual's dimensions. I'd say it's more of a MTM (made to measure) process where the hatter works of measurements. Or even MTO (made to order) where you are fitted to a standard size but choose the block, color, ribbon, etc....Or is this something for the man of such rarefied taste that only bespoke will do?
