Costume Debut: May 2010
Costume Reprised: June 2010, Aeternitas 2011
In May 2010, Irvin finally realized his dream of attending a Harry Potter conference. He went to Expeditious 2010, a very small conference in Ann Arbor, Michigan, hosted by The Fifth House. While there, he finally put his Hufflepuff side into his cosplay and dressed as Cedric Diggory. He dressed as Cedric in student robes during the day, and then changed into Cedric at the Yule Ball. He even had "Diggory" written on his back (which made telling confused people whom he was supposed to be much easier). He saw quite a few great cosplays there, and met many amazing people. It was probably one of the best weekends of his life, and he can't wait to go to another con. He barely slept all weekend, pulling an all-nighter the final night.
In June 2010, Irvin threw a big party called Hogwarts '80s Prom, which he attended in lieu of his actual high school prom. He reprised his Cedric outfit (since Cedric was at Hogwarts towards the end of the 1980s). Since he was the host of the party, he didn't win the McClaggens contest for the first time. However, he did perform with the Dancing Death Eaters as Cedric, which was a tad bizarre.
Cedric became Irvin's go-to outfit for parties. He reprised the outfit again almost a year later at Aeternitas 2011. On Saturday of the con, he dressed as student-Cedric during the morning, as he attended various presentations (including a Sex Ed class). After a few costume changes, Irvin then donned his dressy-Cedric for the Magic Is Forever Ball, and partied hard! He also got killed many times throughout the day.
