There are large gold and crystal torchieres for lighting. A comfy seating area with plush rugs and a few plants give the space some life and comfort. There's even a grand piano in the background space by the stairs. My personal fave piece is the huge framed mirror sections that create the fitting area where the women of OPA do their work on Jeannine. (Can we all get these installed at home?)
So yes, this set flew by on the screen. But in the end, we have to do as much work as necessary to give the director and the actors what they need to feel they're in the right space. It has to feel like they're inside the script...a little Alice in Wonderland if you will. In this case - it's Olivia in Shondaland.
