Boldini painted fast and loose. I find much of his work interesting and this is one of the more appealing studies he did. My students and I sometime look closely at painters like Boldini and others from the Belle Epoch.
This is my class demo from the end of 2015. I tried to get something of her look, without labouring the paint, since that's what is so appealing about the original work. It's therefore by no means a copy, but a homage to his painting. I think it would look lovely in an ornate and broad gold frame.
