Severus Snape

In October 2010, Irvin pulled together a cosplay for the good of his cosplaying community: at TGTSNBN's fall cosplay day he dressed as Severus Snape. With elegant Death Eater robes and a new wig full of "dandruff" (glue), he sneered the day away. He acted out several memorable scenes from the third, sixth, and seventh books. He also inadvertently satisfied one girl's desire for Snape/Lupin when they took pictures of Snape and Lupin wrestling, and the pictures came out looking rather sexual.

Snape became a handy outfit to have, as Irvin could wear it again to Halloween parties at NYU, and to the release of the seventh movie the following month. And, since Irvin is a huge trendsetter, within months there were several Snapes running around.

Irvin wore Snape again at Aeternitas 2011, where he gave a very successful presentation about Snape titled "Snape's Anger." Also while dressed as Snape, Irvin learned how to properly duel with wands.

Snape costumes were so in vogue from 2011 onwards that Irvin left the character well enough alone for five years. But the costume was called upon to present in at Leviosa 2016, in the presentation "Sorcerer's Stone: 7 Obstacles for 7 Books." With some cloaks added for maximum billowing, Irvin took the opportunity to sneer and make snide remarks to all his panel attendees, and ended up a last-minute photo model for another panel about posing for photos in cosplay.
