Apparently released on the internet within the last year or two, some guy(s) taught everyone who was interested how to make armor fairly cost-effectively and not that difficultly, using EVA floor foam sheets, heat guns and hot glue. The result of such efficient tutorials apparently led to a very large conglomeration of DIY Mass Effect costumers this past Dragon-Con.
That’s all fine and dandy, but it turned out that nobody really sought out much originality amongst them all. A vast majority of the male and female Shepards were all wearing variants of black and gray N7 armors. I noticed maybe one or two who busted out some variants of the armor in white, but it pretty much ended up being the same color schemes of whites, reds and blacks.
