Questions about modifying motorcycle armor for Sith armor

[Dakarn]

I'm currently working on Sith armor for costume party later this month. I purchased the motorcross body armor below with the intention of dying the grey foam panels black and cutting it off of the mesh shirt and placing onto another shirt.

What would be the best way to fasten the armor pieces to the shirt?

Also, any recommended type of shirts? I was thinking of just attaching it to a black long sleeved tee with the arms shortened to match the length of the armor pieces.

As for dying it, I took a search around and saw you can use Rit dye on foam.

Any help would be appreciated.

I did something similar for a fan film a while back - the armor just buckled together, though - no mesh like yours.

I had a black jumpsuit that was going to be used for a TIE pilot uniforn, they worked pretty well together.
