what does this painting mean?

[the purple black fairy]

it's by edgar degas.

this is one of my favorites and what is so interesting about it is that it is very mysterious.
i know that degas liked to not just capture a moment in time, but poses. i liked the way the body moved which is why he drew a lot of dancers. but in this painting, niether of the women are dancing. the picture is called waiting but they look more like tired to me.
i don't understand it

it seems to show her stretching before a performance or bending over to calm her nerves. the lady in the black looks like she expects a lot from the girl. interesting piece.
