Thanks to all of you who shared your opinion regarding sleeves. I'm going for it.
Those two sort of crescents to the right of the sleeves are the tassets, or, as they appear to be in the photograph on page 32 of Corsets and Crinolines, sewn together tabs.
I haven't decided on the fabric for final bodice yet, but the finished piece is starting to form in my mind as a post modern pirate blouse. Can anyone else envision linen and raw edges?
