The aesthetics of the post apocalypse survivor may differ depending on the situation that the survivor finds themselves in. That being said there are many common elements among all forms of the theme. The genre of disaster films has been popular throughout much of the 20th century and has continued to be popular into the 21st century. The genre has even expanded into the video game industry forming many products similar to the one featured in the picture above.
Often times a disaster will hit so suddenly that a survivor will have little time to prepare. Therefore, common clothing to be seen in this aesthetic will be everyday casual clothing, or whatever the survivor was wearing at the time of the disaster. The Walking Dead is a great example of this.
