Velma Dinkley from Scooby-Doo
Event(s): Katsucon 2017
I originally only owned a Velma costume for the soul purpose of making other people wear it while I'm dressed as Daphne. I even own shoes and skirts in multiple sizes to accommodate everyone, as well as wigs in several styles.
Before Katsucon 2017, a photographer reached out and wanted to do an awkward, sexy Velma shoot and I agreed. Which resulted in me finally cosplaying Velma myself.
