Born on a mountaintop in Tennessee, greenest state in the Land of the Free…Davy Crockett’s coonskin cap has had a nutria-like population explosion on Milan’s runways. There’s the Davy/Fess Parker classic hat — the one you probably had when you were seven years old that, in the summer of ’55, sold up to 5,000 a day and caused racoon fur prices to skyrocket from 25 cents to $8 a pound. But let’s not stop at the hats. Those furry tails populated exit after exit — on bags, belts, coats,even in the hair. But lest all you fashionistas get carried away, remember the Alamo.
