Leslie Parrish Leslie Parrish is the actress who played Lieutenant Carolyn Palamas in the episode . Parrish was born as Marjorie Hellen , but changed her name in the late 1950s . She filmed her scenes between Thursday and Thursday at Desilu Stage 9 and Stage 10 . According to author Stephen Whitfield , Parrish , when she had to adorn the titillating dress gifted to her by Apollo ( designed by William Ware Theiss ) , was herself completely comfortable and had no qualms about wearing and moving in it , though it were " the crew and set visitors who had all the qualms " . ( " The Making of Star Trek " , p . 361 ) The dress as worn by Parrish has gained somewhat of a legendary status in " Star Trek " - lore as being the prime example of Theiss ' own " Theiss Theory of Titillation " , and has been the eye - catcher in the 1992 " Star Trek Smithsonian Exhibit " . When it was one year later sold as Lot 918 in the 1993 " The William Ware Theiss Estate Auction " , it brought in over ten times the high estimate of US $ 700 – $ 900 , amply demonstrating its stature in lore . Incidentally , Parrish wore the dress again in the episode " The Girl in the Frame " of another Desilu production , " Mannix " , which aired on 16 March 1968 , a half year after the " Star Trek " episode . ( " " , p . 40 ) Parrish herself has expressed immense pride in her " Star Trek " performance in later life , " " Whenever I watch it , I go right back to the whole thing again and cry my way through it . I relive it . My impression of it is that it ' s one piece of work that I ' m very proud of . Of all the work I did , this is outstanding , because it is rooted in something which I believe so deeply . " " ( " " , p . 115 ) Nearly five decades after the " Star Trek " episode had aired , Parrish became acquainted again with it when she was invited to reminisce on her performance for the special feature " Inside the Roddenberry Vault ( Part 3 ) " included on the 2016 " " Blu - ray Disc - set , commenting on recently rediscovered outtakes from the episode , including some featuring herself , most notably the one in which it was divulged that her character was pregnant from Apollo which had been omitted from the episode as aired . She also reiterated her beliefs in the futuristic philosophy behind " Star Trek " and her friendship because of them with " Star Trek " creator Gene Roddenberry , whom she had already met when she appeared in an episode of the by him created 1963 - 64 television series " The Lieutenant " .
