While Working Blues is a tradition at USNA, I think it's time we said goodbye to that uniform. (1) There is no Working Blues uniform in the Fleet anymore -- doesn't exist. (2) It's cost ineffective to make MIDN "buy" this uniform, for which they will completely throw away after graduation. When I was a plebe, we had to buy enlisted utilities (dark blue trousers and light blue blouse) to wear only during the "enlisted" 3/C cruise (a total of 3 weeks our of 4 years at USNA) -- what a waste of money -- it could have been used better elsewhere.
USNA could do well with the NWUs and Khakis for working uniforms and still have dress uniforms as Uniforms of the Day.
Just my two cents.
