Elizabeth, I can answer now. My package was delivered to a neighbor who happened to be on vacation. She brought it over as soon as she got home!
Love it, 9 out of 10. Off one point because the color is not quite as bright as it looks on my screen...still orchid, but a bit darker and more towards the purple end. Still a gorgeous color, just less vivid and pink than the screen shows. But fit, weight, drape, perfect. Just what I need for Southern winter, probably great for you for spring and fall. I'm ordering white very soon!
Fit...I'm often in btw small and medium in things, just depending on sizing. True Size told me small, measurement chart told me 6, which is also small. I ordered small and it is perfect. Fluid and drapey, not what I would call oversized, but definitely not too small. So, I would order the smaller of your two sizes.
I don't think it is a lot of material at the bottom. There is no flaring out or pleating...just a nice, fluid drape. A total winner!
