Since Gren was a minor character in the grand scheme of things, if you take the time to dress up as him very few people will actually know who you are. But back in the day I was a poor for a cosplayer and my costume was easy enough to put together - I just went to a used clothing store and bought a red men's shirt and brown slacks. One blue wig purchase at a costume shop later and BAM! I was Gren!
So maybe I could have been a hotter Gren, but it's all about having fun, right? I've long given up on cosplay, but a small part of me still dreams of dressing up as Gren when he was in drag..
If you have any pictures of yourself cosplaying Gren, feel free to send them to me and I'll add them!
