When I make my cosplay props, I have a lot of time to think and sometimes I like to wonder. I wonder about how practical that prop would be and how the character would use it. It really helps make things more realistic.
Some of those times, however, I go a bit further and imagine stories. One of those times I imagined an assassin, in the future, searching for the weapons he'd learned to use in the Animus. So, this guy (whom I'll still write a story about... one day), would dress in a simple futuristic fashion, but would wear some really old gear from his ancestors. That's the one way I could imagine a guy using a sword in the future. Kinda like in the movie.
And so I built the costume using some props from my Robin Hood costume, from my girlfriend's japanese Assassin costume (and original character called Sora Murasaki) and from my Star-Lord costume. In the end, all I had to do was put it together and take the photo.
I'll leave you a few links to some more pics. I do lots of different things, but if you'd like to follow, that's my Instagram account.
