Adding a blur effect while wearing a suit

[Wasteland Defender]

I have a suit which makes the wearer have a permanent stealth boy effect while wearing it

 

Im balancing it out so that they will have severely drained stats from wearing it

 

I wanted to have sort of a blur effect where it is very hard to see when the player is wearing it, how would I go about doing this? I can't seem to find an attribute that would make it do this. My last ditch effort was adding a concussion effect, but that didnt work.
