On the one hand, it’s normally weird when people cosplay as someone from a game that might suck. On the other...both Horizon Zero Dawn and its main character in particular look cool as hell, so this is 100% understandable.
Cosplay here is by Raven, who made the whole outfit by hand, including the stitching on the leather skirt, which was so tough it needed a holepunch. Photos by Anne-Fleur Boortman.
