Ages ago I saw someone on craftster make a shirt based off this old pattern, and I loved it. I can't find it now, otherwise I'd link it, but I had to try my version.
It's got a circle skirt on the bottom, ties in the front and back, and buttons added under the arm for modesty. I looooove it! Just need to be careful when the wind blows ;P
This is what it looks like before you tied it up, when you pretend it's a cape..
