I took my command (yellow) out of storage in hopes of altering it to wear for the new movie coming out. I never really examined it until now, but wow!- the command color also has that dark line running vertically next to the delta pattern. As I now see in screen caps and close-ups from the exhibit tour, there is a faint lightening of the fabric on the upper right side of each delta. I wish I knew how to post pics (I'm still new here) to show a comparison. I plan on going through the laborious task of cutting out a stencil pattern to place over the fabric to lighten the "line" with an airbrush in order to approximate the film fabric. Also, my shirt was big on me when I got it, and way too big now. So I am going to bite the bullet, and tailor it upward. I have seen that the top seam runs to the shoulder, but in one pic, I can tell Chekhov's seam goes well past his shoulder, so I feel better about it. After tapering the arms, ironing on silver, and hemming, it's on to the denim motorcycle pants and modifying some slip-on Sketchers to approximate the boots! - Oh, and making a whole new crew neck undershirt out of dark grey heather cotton lycra as I have found they have in the movie.
