An actual piece of history, this. This shawl I can see as part of very different ensembles, due to its strength as a stand-alone piece. Lace is tricky, and most any lace shawls are indistinguishable from lace curtains, but here I think this is not the case, since while the shawl's very free in shape, the cut of the hem is clear and intentional, and the upper part sits on the shoulders unlike a curtain would.
Long, billowy garments accompany this piece the best, be it dresses or trousers. Found here.
