Her name is Tjitske Van Vark. She is an 18-year-old high school student from Melbourne, Australia and now she is a hero online, going viral all over Reddit and Tumblr.
In Australia I guess they have something called “Muck Up Day” where seniors dress up on their last day of school and pull pranks. She decided that “Sexy Gandalf” would be a fun costume, and she knocked it outta the park.
