Anne DeCocco By looking at the volume, the length and the expert installation, I'd say these are custom treatments done by a pro. The fabric is called a sheer and there are many, many choices out there to give you this look. A local interior designer would be happy to assist you with having this made for your own space. OR, there are sources, such as JC Penney, who have been putting out sheers for a long time. But even there, these would be custom. They're beautiful!
