THIS IS ONE OF MOM'S (WORN WITH THE BLUE SHOES ALSO LISTED). THE MERRIMAC HAT CO. WAS A PROMINENT AMERICAN HAT MANUFACTURER IN MASSACHUESETS FROM THE 1860'S UNTIL THE 1950'S. RENOWNED FOR PRODUCING HIGH QUALITY WOOL FELT HATS. THIS FANCY HAT WILL MAKE A SPECIAL ACCESSORIE TO YOUR OUTFIT. I'M NOT SURE OF THE SIZE SO I TRIED TO GIVE AN IDEA BY MEASURING THE CIRCUMFERENCE, THE BOW DOES TAKE UP SOME ROOM ON THE TAPE. IT'S A BEAUTY!
