As a slight but valid tangent to this, when it comes to uniforms I think one of the best, with a fewe exceptions, are the judge uniforms from "judge dredd:.
Not advocation judghe dredd, I hate fascism and see the comic as a warning against fascism that few, even in england, are heeding, but if you take the basic judge uniform, GET RID OF SOME OF THE STUPID BITS like the giant eagle shoulderpad and the chain badge, it would make a damn good, practical uniform with all the pouches for holding stuff, the pads for moving around in zero g without hurting yourself and even for combat duty if it were made of kevlar or some more advanced material.
