So Khem Val's armour doesn't visibly show HOWEVER the other day I saw somebody with Khem Val and he was wearing armour and he looked pretty cool! So my question is, is it only certain armour that shows on him or am I missing something ?
I think on Balmorra, in the cantina, you can get the first Khem Val 'armor' customizations. (I don't remember if they have the actual armored one, or just the one with the jacket.) Taris should have the armored ones, and as far as I know, you should be able to go there as soon as you get your ship and 12.500 credits to pick one up.
