Part of the ‘Antique Fabrics‘ series, this fabric isn’t necessarily extinct, but it was more popular in the past than the present.
Twill-weave fabric often used for dresses. Dates back to the 16th century.
Black bombazine was a popular fabric for mourning garb in the 19th century, because its dull surface was deemed suitably solemn for the purpose.
Historically made of silk or a silk-wool blend. It can now be found in cotton, wool and blends of same – although I’ve had a hell of a time finding it in anything other than black or navy blue, so I’m guessing it’s still mostly selling to historical re-enactors. 😉
If you’re looking for a good-enough match, consider bengaline or even taffeta, as long as the taffeta isn’t too lustrous. Or even consider using the wrong side of a crepe satin.
