Just wanted to share the Assassin's Creed costume I made a couple months ago for the Edmonton Expo and for Halloween.
It was my first costume I've ever made and actually the first time I've ever really sewed so it was quite a learning curve. But I got a lot of help and patterns from http://www.assassinscostume.com
The guy who made all the tutorials is awesome and very thorough.
I based it off of Ezio from Assassin's Creed 2 and just tweaked it a bit because I wanted to feminize it
I made the two dual blades out of ball bearing slides. I made a locking mechanism so when I pulled on a string (which was attached to a ring on my finger) the blade would slide out.
It made a really awesome clinky metal slidey noise when it slided out, haha
The blade moves in and out by gravity so all I would have to to do retract them was put my arm up, pull back on the string and they would drop back into hidden position. Really cool!
Anyways I just wanted to share that and would love to help anyone on their costumes too
