Jinkies! It's a SCOOBY DOO Cosplay Group
Here's a set of photos featuring a group of Scooby Doo cosplayers who completely nailed these characters. The photo shoot was done by Benny Lee, and the models include Riddle's Messy Wardrobe as Velma, Jerry Griffith as Fred, Katie Cosplays as Daphne, iObject Cosplay and Law as Shaggy, and Kairos as Scooby. This looks like it was a fun shoot.
