I am going to treat myself to a brand new Whippet. The only thing I'm worrying about is the size. Two of my favorite hats are Dobb's and the size is 73/8. They fit nice. I just bought an open road on ebay , size 73/8, and the hat is tight. I bought another Royal Stetson open road style on ebay in 71/2. The hat is a little big on me but a piece of hat tape under the brim and the hat is very comfortable. I think I will play it safe and get a 71/2.
