I was thinking something along the lines of a dress uniform. The best descriptor for it is 'Future Prussian' but the basis is extremely similar to WW1-era German dress uniforms mixed with modern-day business attire. Just with a far-future twist. The material is colored UN blue with golden stripes and buttons.
Something that is flashy enough to be considered eye-catching, simple enough to be considered practical, and something that would fit the 'all the punk' setting that I'm making. Depending on the person's dominant side, there is a 'future-tech PIPBoy' style wrist PDA on the right or left wrist, designed with a ruggedized touchscreen and augmented reality compatibility with the ability to add holo-screen capability if the user desires it.
The person wearing it can be a man or woman and is an enlisted soldier (the equivalent of a private 1st or 2nd class). At the person's hip (depending on the dominant side, it would be the opposite of the PIPBoy style wrist PDA) would be a
'tactical sword' in a simple sheath while a pistol holster with a simple semi-auto pistol* occupies the opposite hip.
