Cyclops

Irvin's favorite show as a kid was X-Men Evolution, so when he had a cartoon-themed 24th birthday party, there had to be an homage to that show.  Irvin therefore decided that his second outfit of the party would by Cyclops - Scott Summers, the team's fearless leader.  This costume probably involved more work than any other Irvin's done to date - the entire thing had to be made from scratch.  Under his friend Deanna's mentoring, Irvin sewed the yellow X and the backing for the shoulder pads, attached them to the body suit, and made the yellow boot covers.  He even had to dye the gloves yellow - yellow clothes are surprisingly hard to find, as Woody and Misty can attest.  But the end result, if he does say so himself, came out really cool.

After all that hard work, Irvin was determined to get maximum mileage out of the costume.  He donned it again to go see the new X-Men movie that May, X-Men Apocalypse.  The following month, June, he wore it to AwesomeCon 2016.  There was a host of X-Men at the convention, though none from X-Men Evolution, but several fans understood which specific version of Cyclops the costume was, and were very impressed.
