Girl Painted on Wall Optical Illusion

Below is a very interesting optical illusion effect. The questions for consideration in regard to this image are as follows:

Are the clothes painted on the girl?

or

Is the girl painted on the wall?

Artist: Martin Armand

This is the image as I found it on the web. There was no head to give me a clue. My first impression is that this is a real girl with clothes painted on her.

However if you look closely it would be easy to believe that this girl was actually painted on the wall.

What do you think?

Update: This is the work of Martin Armand you can find more of his artwork here.
