I'm hoping someone might be able to clairfy something that's been puzzling me.
I notice that many mass-market bits of menswear, particularly things like rental-type tuxedo trousers, are made with a somewhat wiry sort of woolen or blended fabric that tends to hold its shape quite well well.
Yet when I go fabric shopping, for the best-deal remnant places on up to those charging a small fortune and presumably supplying New York's tailors, almost all of what I encouter in the woolens is very soft and drapy - if I understand correctly, made of fine highly twisted yarns.
So the question is, what's the wiry stuff called and where can I get it (either by mail or in NYC)? For my purposes - dabbling in making ballroom dance constumes - I really want something that holds slightly artificial shapes as well as those rental-type tux trousers. Ideally I'd like to find it in both wool (for when it counts) and poly (for everyday practice)...
