Appendices . Background information . The uniforms seen in the films " Star Trek " and " Star Trek Into Darkness " were designed by Michael Kaplan . They are quite different from the pilot uniforms seen in and . It can be assumed that Nero ' s time tampering had something to do with the shift , although the real - life explanation is that the uniforms seen in " Star Trek " were intended to associate the audience with the much more familiar Original Series uniforms seen through the late 1960s , in contrast to the pilot uniforms , which were only seen in two episodes . A similar situation arose in where Leonard McCoy is shown in a flashback video wearing an " Enterprise " tunic whereas , historically , he should have been wearing an earlier pilot episode uniform . The filmmakers expressed surprise in " Star Trek - The Art of the Film " that the classic uniforms were never used in a film . Kaplan explained that he selected red for the dress uniforms because of the strong patriotic feel the color gave . ( " Star Trek - The Art of the Film " ) In " Into Darkness " , Kaplan noted " " There are a lot of high - powered meetings with Kirk and officers , and I wanted to add a level of sophistication , where – like any military service uniform – there would be different parts . So they now have dress uniforms , and shuttle suits , which they travel in . " " Apocrypha .
