Well, it's a double knit jersey, 68% viscose, 27% polyamide and 5% elastane.
The 5% elastane tells you that it's fairly stretchy
The only other thing you would need to know is the weight - gms per square metre (or American ounces per square yard).
Unfortunately, very few RTW clothes labels give you that, and most rolls of fabric for the retail market don't tell you either.
That's why buying buying fabric by mail order is so difficult, you really need to be able to see and feel it. But if there are no fabric shops near to where you live you have to rely on however the vendor describes it.
