there had to be something - a jacket, perhaps?
Again I browsed my Arnold (Patterns of fashion, ISBN 0-333-38284-6), and found this interesting sleeve cut:
It comes from a Spanish book (Geometria y traca, by Francisco de la Rocha Burguen, 1618)
So I made a simple front, a Spanish sleeve and a pleated back.
After having made the pattern, I wove the approptiate amount of material, using the weave I showed here
I used the same warp yarn as in the collar, merc cotton 30/2, but in two shades. For weft I used a softer merc cotton, still 30/2.
... as one cannot use a jacket like this over jeans, I also had to make a dress to go with it :-)
I found some shot doupioni silk in a slightly darker shade - and this is the result:
Now I only have to wait for the perfect party to wear it...
