Although buying armour is probably gonna be simpler, go build it yourself. This takes months, but if you practice alot your armour is gonna get really good. And it's fun, too! (except pepping. i hate cutting and folding. Glueing is fun, but scaling, cutting and folding sucks.) but the rest is fun, and you#re probably gonna end up with 100$. Trust me, buying armour is expensive. Also, don't buy them halloween costumes, they suck too.)
Make you own!
Also, don't build E.O.D. I don't like EOD
