Aaaargh! Y0, ho, ho and a bottle of brass monkey. Moses made a fine, fine pirate.
The hat, you know about (if not, scroll down a little ways). The shirt is a resized women's shirt; the pants are resized girls pants (they should be capris, kind of rouched at the bottom, but they are just short of normal length on him--I took in the waist), I got them both at Goodwill. I made the vest out of the same faux leather as the hat and bought the skull scarf (tied at waist) at Walmart. My brother gave all the kids one of those Nerf swords ages ago. Aargh.
