I did read ML's book long ago, and while it may not have been accurate in some respects I certainly did develop an interest in Grainne from it! :-)
I've read two books since on female pirates, one by Barbara Sjoholm ('The Pirate Queen') and another by Joan Druett ('She Captains'), and that's where I picked up the detail above. Whew! I'm glad I'm on the right track - at the very least we'll be the only accurate female pirates in our group of moviegoers! (I may get to use this costume again for a local theatre production later, so accuracy = better chance of getting the job) So it would appear from the snippets of film showing Elizabeth's new costume in POTC2 that they actually got it pretty well right! ;-)
I'm using the Eagle's View pattern for the breeches, but would you recommend a particular weskit or frock coat? I was going to use the Simplicity one, but I don't like that the coat isn't lined (nor is the back of the vest, for that matter).
I can't wait! We're also getting hat blanks, cutlasses, and baldrics (not sure if we'll make, or buy).
