The image shows a person standing in a field with
green vegetation, wearing a furry hat and what appears to be a flannel shirt. The individual is smiling at the camera. There's no obvious indication of cosplay or any specific reference to
Gravity Falls or Wendy from that series in this image. If there are specific details or elements you believe relate to cosplay or Gravity Falls, please point them out, and I can provide more information based on those observations.
