I tried again just in case but they are still saying it will be tomorrow.
I did get a bit more information on the "costumes." Please keep in mind this was from a phone cast member who wasn't quite certain himself, and (sorry guys) kinda had a "male description" of clothing if you know what I mean.

He did try, though!
There will be four available.
The one for girls is called the "Pirate Wench." His description was: "dress and things over your shoes like boots, at it is like an old style dress"
The second he called the "Boney Pirate" with a shirt thing that comes down to your hands with a skeleton on them."
The third was "Capt Jack" which included "a shirt and dredlocks with a hat."
And he couldn't even remember the fourth one, "Some Pirate Captain or something" (Um...I sure hope it's a Pirate at the Pirates League).
(Please understand I'm smiling, he was actually trying to be very helpful, it just made me think of my husband trying to describe our daughters' clothing. He knows they left the house dressed and not exposed, and that's about it!)
My "guess" from nothing other than the vague information he had was that they will be an awful lot like the pirate costumes Disney already has out there, or similar to these (totally guessing, I just wanna see how close I get!)
Pirate Wench Guess:
(this was actually posted on July '08 in a Bibbidi thread, by OneTreeHill addict, so if Disney made this before it's more likely what they'll have again, or close to it)
Boney (I think they mean the Cursed One) Pirate Guess:
Capt Jack Guess:
Mystery Pirate Guess: I'm saying Capt Hook, as your choices for facial effects are "Cursed Pirate, Captain Hook or Captain Jack"
And here is my guess at what some of the accessories are that everyone gets:
My daughter and I were really hoping they'd have this one:
but it doesn't sound like it
If anyone hears about a different girls' option other than a "wench dress" please let us know! My little piratess does NOT want to wear a dress!
