-One of the bad things about starting so late is the uniform discussion has probably already come and gone. I did notice the vertical lines but not the horizontal lines. When do the new uniforms come?
Let's see, Picard alone gets it in "Booby Trap", Riker and Geordi get it in "The Enemy", and Beverly switches to a one-piece with a seam down the middle, Worf and Data get it in "The Price", Beverly's uniform loses the seam in "The Defector", and O'Brien gets it when he reappears after several episodes in "The Hunted."
The rest of the crew magically receive them right after Riker gives the order to fire on the Borg cube.
