Plastic wrap
It looks like this woman decided to cover herself in the same plastic wrap that older people use to cover their furniture. In fact, we know that’s what she did because if you look closely, we are fairly certain that’s a couch behind her. Is she trying to tell us something about her pregnancy and the couch?
Maybe she is trying to make a statement about the environment and how we are killing our children with pollution. See if that was her reasoning, then we understand that message, it just took us a while to get it. She could have made it much more clear, maybe without the strange pose.
