My take -- no reason to have two tiers of working uniforms. The Brits (similar to utilities, but look a hell of a lot better) and Coast Guard (2 piece coveralls) have it right wrt working uniforms. Either of those would be good, and ditch the other "tier." The NWU is horrendous, too heavy in hot weather, and really expensive for a working uniform.
Service uniforms: Either stay with khakis for E-7 and above and peanut butters for E-6 and below, or stick with summer white/johnny cash. But do either or. Having 3 sets of service uniforms is silly, and the all-purpose khakis mean that the other ones sit in the closet.
Dress uniforms: Keep current chokers/SDBs or go straight to SDKs only. Again, no need to have an all-season dress uniform and then specialty seasonal ones.
PT gear: Ditto on contracting any number of sports companies to make a comfortable, good fitting PT uniform.
