Top hats, such as The Collapsible Silk Top Hat, are still the choice of men's formal dress hat for important and once-in-a-lifetime events such as weddings, galas, and graduations. The Collapsible Silk Top Hat is a truly classy version of this hat, fully lined, of course, and it pops into shape with a flick of the wrist. The less-pricey version can be had in wool felt from Scala Hats. They call it The Mad Hatter, and it's a traditional top hat, ready for any dignifed appearance you're forced to make.
