Alec Lightwood (Shadowhunters)

Irvin and his friends Angelica and Sara were all big fans of the Shadowhunters TV show (along with varying levels of fandom for the corresponding books).  So for BookCon 2019, they decided to pay homage to recently concluded show with a group Shadowhunters cosplay.  Angelica was Izzy, Sara was Clary (with uncooperative red hair dye), and Irvin was Alec.
