Caryn,
You are right, I DID ask to see the other hats, so that was indeed my request. To measure a hat's size, you need to measure the INSIDE of the hat, right along the seam where the crown meets the brim, or a the very edge of the lining. Take a soft tape measure and go slow...best to start at the back seam if the hat has one, to give yourself an end point. The closer to the 1/4" the better, as 1/4" can make a difference in the way a hat fits. Measure twice to be sure!
