Ro sported a command color head band for quite some time as well. I never saw anyone else wearing one of those
Oh, good catch.
Obviously, Beverly also sported a blue lab coat.
B'Elanna had a gold engineering jacket, with pockets for her tools or spanners or whatnot (and to hide her prego belly).
Picard's Captains vest and Captains jacket (sweet suede) are presumably for Captains only, but never discussed on screen.
