The tunic shown in that auction image, BTW, is misidentified. The uniform being worn by the Vulcan was designed by Robert Fletcher for ST:TMP - it's one of his right down to the "belly-warmer" belt buckle. Fletcher didn't work on the aborted second TV series. The uniforms to be used for Star Trek Phase II
were the original series uniforms and some variations, all in the original series colors - many were fabricated and have found their way into the hands of collectors.
