A note on measurements: I like to give measurements on items rather than a numerical size as I find this to be a much more precise way of determining size. If the garment I have measures the same as a garment you have, you can be assured of a good fit. If you have any questions about how I did the measuring just email! PS don’t forget YOU must measure at least 1-2 inches smaller than the garment does for comfort! :) Vintage 1950S Bowler Medium Brown Felt Equestrian Hat Six & Seven Eighths
