Costume Debut: June 2011
Costume Reprised: July 2011, MISTI-Con 2013, July 2013, July 2014
Coney Island's Mermaid Parade in June 2011 seemed the perfect opportunity for Irvin to begin his summer cosplay line. He chose to cosplay the last Triwizard Champion, Viktor Krum. He would be cosplaying Krum during the Second Task, when he half-Transfigured himself into a shark. For clarification, he labeled "Krum" on his chest, and used kids' swimmies for the shark bits (which left him with no skin on his upper arms, and some very odd tan lines). And, appropriately, he met a Giant Squid at the Mermaid Parade.
The outfit must have been brilliant in its simplicity, because it was one of Irvin's best-received outfits to date. It was so popular, Irvin decided it would be his outfit for the midnight release of the last HP movie. So on July 14th, Irvin met up with over a hundred costumed friends from TGTSNBN, and they traipsed all over the city, causing disturbances wherever they went, and then wreaked mayhem in the movie theater for hours before the movie.
The necessity for such an outfit was a pool party at Aeternitas 2011, so Irvin wore the outfit to the pool party at MISTI-Con 2013. He even had a shiny Durmstrang pin procured at the Wizarding World. Partygoers quickly learned to scatter when they saw a shark fin approaching, since Irvin approached racing games like a true Triwizard champion.
The outfit was again reprised when the Scholastic Store celebrated Harry's birthday in 2013, and promised free signed lithographs of the new cover to attendees in costume. Since this was the end of July, Irvin decided to wear this seasonally appropriate outfit, which was once again met with great appreciation. It was also met with envy by the other cosplayers, who had actually dressed in robes for the event and were perspiring in the summer heat. Irvin got to meet Arthur Levine while dressed like this, and got his signature and a photo with him.
A staple of Irvin's costume wardrobe now, as it is very summer-appropriate and very easy to don, it reappeared the following summer (2014) for PotterCon, a celebration of Harry's 34th birthday. It was well-timed, since this was right after Viktor Krum finally achieved his lifelong ambition and won the Quidditch World Cup for Bulgaria.
