Pizza rat may have proved that anything can be turned into a sexy Halloween costume. But an Australian teen's provocative take on a "Lord of the Rings" character is definitely thinking outside of the box.

Tjitske Van Vark, an 18-year-old high school student from Melbourne, Australia, "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," Buzzfeed reported

That outfit — a "sexy Gandalf" — caused quite a stir when Van Vark posted a photo of herself in the getup, which took her less than a week to make, on Tumblr. The post went viral on the site, causing her to triple her followers, and for Tumblr even to feature the photo on the front page of its site, according to Buzzfeed.

"The absolute best thing though has just been the general thirst for Gandalf I’ve created,” Van Vark told Buzzfeed. “Honestly, nothing is better than seeing people exclaim ‘I want to f**k Gandalf’ because of me!”
