Bought a size Small and I was pleasantly surprised at how much I love this blouse. Tucked in, or belted with a wide belt and it looks great. And it is so silky feeling. It just flows so nicely over body. Sleeves nice and long. Collar stays put. It is not see through at all. Highly recommend.
For reference, I am 5'4", 120 lbs., 34A bust. Happy about this purchase.
