Let's look at this logically.
Off base, (ie: in the trees and weeds), variations of green/black/brown are de riguer for the sensibly dressed fighting man. However, in a more concrete based environment, (ie: within the confines of the station), variations of grey/blue/black are his dress of choice.
So, it's really rather simple. You are better off wearing blues if your rear never leaves the station thus all the tech types, supply and admin types, scuffers etc. should wear blue at all times while the more daring, better looking aircrew and Regiment types that venture past the wire for something other than a pie and a pint should wear green stuff at all times because they may be expected to leave the station
on "business" at any time, (Oh, and blues look so wimpy...)
Ladies, if you have this much time to argue about your bloody wardrobe you could pobably be out trying to pass that fitness test you all complain is such an imposition on your time!!!!!
