These, on the other hand, are drapes. Floor length, more formal, more gravitas. Drapes like these are almost always lined, and are sometimes inner lined as well. That extra lining inside the drape is often a lightweight flannel. Not only does it give the fabric a lovely “drape,” but it’s a great insulator when the panels are closed. Drapes can be operative, which means they open and close, or stationary, which mean they do not move and are decorative only.
