Yup.  If it was just the sweatband, most western wear stores have stretchers, but for the crown, it needs a real pro.  I once watched such a guy "making" custom hats for walk up customers at a gun show.  He started out with something that looked a lot like what Hoss Cartwright used to wear, then put the crown and brim shapes on that the customer wanted.  Very interesting to watch...
