Another LoL halloween costume idea

I got a dress like this from Charlotte Russe for $5.

I've been trying to decide what to use it for, so here's a half-assed halloween costume idea... sexy female astronaut teemo.

Plus, I already have (something like) these:

So, to complete the costume, I would need:

1. A helmet.
With modifications to face shield, adding ears, etc.

Another option would be dealer visor + ears:

2. A pair of snowboarding mittens, painted silver (or buy silver mittens...). Or could do something like this:

3.  A big (silver) belt.

4.  Dryer vent hose (not required)

5.  Face paint.

6.  And making the blow gun/staff.
