Tjitske Van Vark is an 18-year-old high school student from Melbourne, Australia. She recently dressed up in costume for her school's "Muck Up Day" — an Australian tradition where seniors dress up on their last day of school and pull pranks.
Van Vark went as "Sexy Gandalf" and posted it to her Tumblr, writing, "Our last day of school involved dressing up and I took it upon myself to be the sexiest one there."
Her photos blew up instantly. "Within three days my follower count had more than tripled, I've received far too many wonderful messages," Van Vark told BuzzFeed.
Her photo was promoted into Tumblr's radar, causing it to trend all over the site.
She was even featured on the front page of the site.
In real life, though, she said most of the students at her school didn't really see the humor in it. "That might have been because most of them were very hungover from the previous night's parties at that point," she said.
"This costume actually only took me less than a week or so to make," she said. "I've been casually costuming for a while now. It was just a matter of working through the steps, finding motivation and hoping for the best!"
"The absolute best thing though has just been the general thirst for Gandalf I've created," she said. "Honestly, nothing is better than seeing people exclaim 'I want to fuck Gandalf' because of me!"
