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!!
I was in the Air Force... when they introduced the shorter blue overcoat, they specified it had to always be zipped when worn but I don't recall further guidance on how far up it needed to be zipped. I must not have been the only one confused based on the wide range of zipping I subsequently observed....
