Have you been to San Diego Comic-Con?! It's such a big part of popular culture, and has grown so much since it's early days as the Golden State Comic Book Convention in 1970!
I haven't cosplay culture has always been on the fringe of my social circles though, I see a ton of it on Reddit.
There are some *amazing* cosplay creations and creators! Do you have a favorite? A specific character or costume?
I personally love Geralt from the Witcher series, anyone who can resemble him is some kinda cool guy
I must admit I'm unfamiliar -- I only know that the Witcher Saga is huge -- isn't it a series or about to be?!
It is going to be on Netflix soon yes!
Do you know who is cast? I think that's why/how I heard about it -- and the fact Netflix and I are friends! Crazy it's inspired films, series, video games, etc....oh, and cosplayers! 
I'm not sure actually, it must be nice being such good friends with Netflix haha. Cosplayers are like furries that don't get weird with it.
That is hilarious. The first time I heard about furries, I seriously thought it was a made-up thing. But, alas.....many of those creatures do gather on the internet or conventions....
