3. sword (it can be either plastic, LARP, or real)
4. helmet (use cardboard or paper mache to make the helmet)
5. armor(armor is optional)
Step 2: Helmet
you can make this helmet from this link http://www.instructables.com/id/Cardboard-Armor/step2/Helmet-part-1/. or you can make your own helmet out of cardboard or paper mache.
Step 3: Gloves
gloves are an easy step to a spartan outfit. all you have to do is go to home depot and get some gloves. or if you have gloves, just use those instead.
Step 4: Shield
the shield part is going to cost some to alot of money. but basically all you have to do is go to amazon.com and type spartan shield or go to this link http://www.amazon.com/Movie-Leonidas-Spartan-Replica-Shield/dp/B000V5KMGQ/ref=sr_1_4?ie=UTF8&s=sporting-goods&qid=1267568586&sr=8-4.
Step 5: Sword
the sword part is going to be easy. just buy a plastic sword from a local dollar store, or buy one online. if you get a sword from online, they might offer a LARP or real sword, which is perfectly fine.
Step 6: Armor
again armor is optional, but you can either make armor from this link http://www.instructables.com/id/Cardboard-Armor/step1/Breastplate-and-Backplate/. or you can buy real armor online.
