Looking for build tips and tricks

[Kaburn1cas]

So I've never done a costume like this before and I need help with basic material and what not, where should I start?

What costume are you working on?

Each costume type has a dedicated forum where you can maintain a build log, communicate with prospective and current members, study other people's builds, source reputable vendors...

We have character-specific web sites called "detachments" where you can find armor vendors and all the info on how to put it all together. Do a ton of reading/research into the costume you want to do before buying anything. You can find the list of detachments here:

Stay FAR AWAY from Ebay, Amazon or any other web site that claims to make approvable armor.  Almost all are scams or sell complete junk.
