Due to the spread of the corona virus in the world, the mask gradually became a new clothing for most people, and the idea of this "Installation art" came to my mind. The clothing, all of which are attached to the human body (in this particular case = female) by a strap, are the main subject of this "Installation art". A picture of the boundary between the world outside the house and inside the house, and at the same time the boundary between life and death.
