I got this fancy dress in exchange for playing for a fashion show at a little boutique in Ithaca — and for modeling the dress at the show. It’s made of two different rectangular shawls, silk, with velvet burnout designs. The boutique owners designed the fabrics.
Here’s what it used to look like — rather shapeless, and rather more narrow than I am.


I took it apart this afternoon, and started pinning it to my dress form to see what I could do.
Here is the main piece, with bust darts.

There’s a triangular hole under each arm from folding the dart. Also, while the main piece front and back meet at my waist, they don’t at my hip. (Oh, and yes, that’s a pair of aluminum knitting needles holding up the form. And that’s one of my speaker stands. It has holes where you can slide in a little bar for added stability when the top part of the stand is raised.)

Here it is with the sleeve pinned back on and with the lower skirt pinned at the side. I’d still need another piece of something to fill in the triangular hole — I have some black velvet from another non-fitting dress that I could use.

I’m not quite sure how to go about the construction. Certainly not a back zipper. Maybe a side zipper, but it would have to go at an angle down from the waist so as not to mess up the insert fabric’s pattern. I’m thinking maybe ribbon ties. And if I could somehow do that insert fabric so that it’s not actually stitched to the main piece, then that would allow more freedom of movement. No one would know how silly it would look underneath, with two rectangles joined by a band of elastic or something. I’d also probably need to find some matching fringe for those insert pieces.
Unless I don’t use the sleeves — I sort of like the look of the split cap sleeves. In which case I could sew the sleeve rectangle to the other rectangle (the sleeve rectangle isn’t long enough to reach from hem to waist) for the inserts, or else (aha!!!) just transfer the sleeve fringe to the inserts! There we go.
