Flying Dutchman crew costumes from Pirates Dead Man's Chest...

In Pirates of the Caribbean: Dean Man's Chest, 'Captain Jack Sparrow' must face the return of 'Davy Jones' and his motley pirate crew of the Flying Dutchman ship.

These original costumes were worn in the movie by two of Davy Jones bizarrely marine-life altered crew.
