The concluding black-and-white episodes of the Diana Rigg series had a more than usual tendency to show off her figure to fullest advantage.  Such is the case especially with "A Sense of History," in which she dresses in a leg-revealing Robin Hood outfit, and "A Touch of Brimstone," where she wears next to nothing as the Queen of Sin (and is attacked with a whip, to boot).  "How To Succeed...At Murder" has her in a bodystocking/leotard, practicing ballet for a good portion of the story.  And when she isn't dressing down, she's quite the clothes-horse, wearing a gorgeous white pants suit, for instance, in "The House That Jack Built," a memorably striking bit of surrealistic sci-fi.
