Rikun: for the wig and costume i wouldn't pay 100$ for all of it, if you go to the thrift stores you can possible find stuff that will be cheaper and then alter it to look like your character.
geemrpeabody: check etsy and other How to through google and such engines. also (i'm not technically minded either) but post on cosplay.com and again etsy and see who's out there. I received my hidden blades thou a guy named john storms in etsy and he might know of someone or can make them.
for PEACE BONDING---------
THEY ARE CHANGING THE RULES! YOU HAVE TO READ THEM WHEN FAMINE COMES AROUND AGAIN.as it is- IF it's an air soft gun, or regular plastic gun or rifle-
*The tip has to be plugged!-as well as bright orange that you can see from at least 20 feet- so you might have to make the tape go down more of the barrel. (or just use a bright neon colored gun) ((i know it sucks but it's the rules so everyone is safe))
*The Trigger CAN NOT work! (if it has a slide on it-block it or glue it shut)
*NO AMMO-either in the clip, on the gun, or on your person!
*if you have a clip in your gun-EVEN IF IT"S EMPTY- you have to make sure that nothing can get in it(so if it has a bottom take it off!)
*basically it can not fire anything, look like it can, or even look like it might be able to fire.
WEAPONS:
*NOTHING REAL!!! that includes bows, with stings (if some one cause sting it and use it-it's a no go!)
*live steel-NOTHING LIVE STEEL!!! even if it's paper thin-it can possible hurt someone.
*wood-Has to be light weight!
for foam guns-still needs to have a bright orange tip! and it's up to the fanime peace bonder(as each gun is different) - as some of the stormtroopers were fine, but there are a few things that were not form other cosplayers- check with them and please don't yell at them.
