Part of the ‘Antique Fabrics‘ series, this fabric isn’t necessarily extinct, but it was more popular in the past than the present.
A fine poplin with silk warp and cashmere filling.
I spotted this one mentioned in the reprint of Bloomingdale’s 1886 catalog – some of their ladies’ dresses were available in sicilienne. It was considered rather superior to regular poplin.
Unfortunately, I can’t find a reliable source for a picture of this fabric and it’s definitely not for sale. For a good-enough match, I’d use poplin – but as nice a one as I can afford.
