I believe this is aizome (indigo-dyed). The fabric appears to be a soft, raw silk-like material with horizontal slubs, and features a floral arabesque pattern. I think it's silk, but it feels substantial, like cotton. The more I look, the less sure I am whether it's silk or cotton... The lining is all silk, and the basting thread is also silk. The color is like indigo layered on indigo, and the pattern is large but elegant.
