The blouse is new with tag and in an excellent condition. It comes with a detachable Jabot collar (can be attached with pressure buttons).
It is from the taobao brand Yellow Peach Glutinous Rice Balls and is made of satin fabric and has a straigt shape.
The color resembles the color of the stock photo, even though my camera can't capture it very well (it looks different under different light sources).

The taobao listing said it would fit a bust/waist size of 116 cm. I don't think this is realistic.

I would assume it fits a bust/waist size of around 95 - 110 cm. (55 cm when laying flat)
