I made this a few weeks ago the day before DS went to a pirate/mermaid story time at the state library. Luckily my stash is far too big and there were enough pirate-y things tucked away!
The pants are just my favourite basic pants pattern which I then turned the bottoms up on and made the zig zags, did a lot of snipping and topstitched them to hold. They're a bit rough but that's pirates for you
The vest was from a tute from made which was awesome http://www.danamadeit.com/2008/07/tutorial-pirate-life-costume.html, and we added some pirate-y buttons (cause that's all I had).
He was pretty stoked.
