What material does this skirt seem to be made of, according to the description?

Silk, of course: "Tommy Hilfiger's plaid-print skirt is made of crisp silk for a luxe look this season and beyond!
Silk; lining: polyester"

I got it today, and the skirt is made of pure polyester. And not the silky, nice polyester that you get these days. It's made of *raincoat* material. Very stiff and noisy. I guess that's what they meant by "crisp".

I'm going to return it, but I'm very disappointed at being misled like this. Should I complain to Macy's?
