I liked the new DS9 uniforms, but only had one issue with them. it seemed that there was no standard for where someone could zip/unzip the jacket to. Some characters wore it zipped just to the bottom of the grey portion where other wore it zipped further down. As a military man that drove me nuts!
One of the few differences between Starfleet and today's militaries. But those uniforms could be worn with the sleeves pushed up or with the branch-colored duty undershirt unzipped if environmental or work conditions warranted. In that sense, they doubled both as standard duty uniforms and work fatigues, IMO.
