I’ve worn hats all of my life. I know because my mom has a lot of pictures of me wearing them as a boy. Hat stores, real hat stores, are very rare in the United States. Unlike the baseball cap store in the mall these are places where you can buy a fedora, have it cleaned, blocked and repaired.
I maintain a list of hat stores for my friends at The Fedora Lounge. This is where they can download the file.
