Terra's Armor Help?

[Terra]

I am going to be cosplaying Terra from Birth by Sleep. I don't think I'll have is done in time for the convention, but if anyone could help me out I might could. Any tips/suggestions for making that armor? I'd prefer something... not metal. I'm not very strong.

Craft foam. It came from on high to shower us with its magical abilities. lol

I used it to make my Vegeta armor
