/cgl/ - Cosplay & EGL

My Miranda costume came in the mail!
I plan on using my own hair but dyeing it darker, so here's how I plan on styling it for the con.
I still need to add some snaps to the shoulders/sleeves so they'll stay on, adjust the belts a bit as well as airbrushing the hexagon pattern all over the thing...
I'm not looking forward to taping it all off to do that. Any suggestions on how I should go about making the pattern on the costume, or is taping it all completely off + airbrushing my only option?

Pic related - me and a small example of what I'm talking about with the pattern.
