Alright, so the feel I'm going for is stealth/slicer/spec ops. It'll be in the modern era. I am 3d printing all the armor in pla plastic (if that material is acceptable and there aren't any major downsides I'm unaware of).
-The helmet is going to be designed after the assassin helmet.
-The gauntlets will have a couple secondary weapons, a data spike/comp stick/whatever-else-they're-called, as well as buttons and other greebles for slicing.
-As far as armaments' go, I'll have a TL-50 heavy repeating blaster, a DL-18 as a sidearm, and a knife (or knives; you can never have too many) for melee.
-I'm hoping to get a full flightsuit akin to the Air Force's and dye and modify as needed (I'll definitely have some questions on what pockets need to get cut among other things... but I'll cross that bridge when I get to it).
-For the vest... I have no clue what to do. I am not good at and really don't like sewing, so if anyone has any suggestions that'd be great, but for now I'm planning on buying either a custom one or modifying a plate carrier.
-The plan as it stands currently is to be a chiss. I am going to attempt this using fingerless gloves and making my hands blue underneath. I'll also probably try to incorporate the chiss ascendancy emblem somewhere on the armor. Lastly I will try to make my face blue and eyes red as well, but the goal would be to tell the story without having to take the helmet off or use potentially harmful contacts. This is all still a concept and I may opt out before I even get to that point as it will be one of the last steps.
Here is the color scheme I'm shooting for. I will be painting a sign/sigil on the forehead of the helmet and a different design going over the front torso armor pieces. Those will be in red with purple or blue as a 3rd color if the design needs it.

All comments and/or advice will be greatly appreciated!
