Juvia Lockser from Fairy Tail cosplay!
I made her Teru Teru Bozu doll, which is a little traditional handmade doll made of white paper or cloth that Japanese farmers began hanging outside of their window by a string. In shape and construction they are essentially identical to ghost dolls, such as those made at Halloween. This amulet is supposed to have magical powers to bring good weather and to stop or prevent a rainy day. "Teru" is a Japanese verb which describes sunshine.
Juvia, because she is a Rain Woman, often made these to try and stop then rain that followed her. Fortunately, since joining Fairy Tail, this weather trait has stopped.
