Thank you! Are you using the same foam to make yours (I didn't see it in your costumes, but maybe I just missed it)? If so, I wouldn't worry TOO much about attaching things. I feel like hot glue works REALLY well. I'd at least give it a shot before you remake.

Heh, I think it does go all the way down in the normal N7 armor, just not in Liara's (or Ashley's, since they're just recolors of each other I think). So maybe not wrong depending on which one you're doing
