GF Armor questions?

Alight, so as you can tell i'm new to the thread, and I have a couple questions.

I'm starting to get into this sort of scene and might buy a stormtrooper suit as I've always dreamed of owning one (who hasn't?).

So, I found a GF suit, and I'm aware that this suit is quite rare. Just wondering if you veterans would have any precautions, worries, or any advice.

Thanks!
