This is a karinui - an unfinished kimono that has been cut into the panels and basted together at the seams but has not been completed or lined. It's impossible to tell why this was not completed, but it could have been a shop display sample or might have been a cancelled order....
It is not easy to complete this as a kimono, though a karinui certainly gives you a head start on the attempt rather than beginning with a tan (continuous bolt meant for a kimono).
This is synthetic fabric with a crepey texture in a deep eggplant purple.
The patterning is in angular blocks and includes jeweltone florals and several birds with wings outstretched. Gold accents.
If you decided to take the basting out, you'd have about eleven yards of fabric to use for your sewing project. Great for scarves, pillows, a dress - even a blanket or quilt top.
