Galactic Trader Pimp

Or Mudd's Women, the space hooker episode. According to Solow and Justman this episode was in contention to be the pilot for the series.

Costume wise: Finnerman used so many different coloured lights that we can't tell what colour Maggie Thrett's outfit was supposed to be. Was it green, gold or taupe? Only Spock knows for sure because he certainly oogled them enough. And what about Vulcan's not being able to show emotion? Take a look at this face. And speaking of that dress, read an excerpt from Solow and Justman's book.

"Actress Maggie Thrett was on of the three space hookers who boarded the Enterprise in the first-season epsiode, Mudd's Women. Gene had spent a goodly amount of time "making their costumes better." But as we filmed Maggie writhing about and attempting to entice our heroes, one of her breasts popped out from behind what little bodice was left of her costume. She quickly stuffed it back in, smiling ruefully. It didn't stay put, however, much to the crew's amusement and her embarrassment."

Perhaps this is the costume in question? And is Bones a dirty old man? Ah, well. You'll just have to watch the episode to find out.

The Creators - TOS

The man responsible for giving the show the creatively unique dramatic lighting and camera angles was Gerald Perry Finnerman. He was directed by Bob Justman to light the sets with wild colors like magenta, red, green and any other color he could find. Bob Justman told Jerry to "go overboard". Backlight the women and make them more beautiful. Take some chances. Throw those wild colors behind the actors, especially when they're in a close shot.

William Ware Theiss was the shows costume designer. Bill designed clothes only as he didn't "do monsters" but he was challenged enough in that he couldn't simply buy clothes for the actors off the rack. Instead he lived in a small apartment one block from the studio where all his creations were put together by an army of seamstresses. Said seamstresses worked throughout the night and the costumes were carried to the set just in time for the actors to shoot their morning's work. Since the Desilu studio gave Bill very little money, he was hard-pressed in finding interesting fabrics within his price range for his other-worldly creations.
