In an episode of Columbo, Sex and the detective,

Lindsay Crouse sees her lover cheating on her with another women. So her plan is to murder him. She buys a very sexy wardrobe to lure him into a sex game. She tries on a black teddy, which covers her torso. Yet in the murder scene she's wearing a black outfit with the dress cut in a V down to her abdomen. Exposing a lot of bare torso. She couldn't be wearing the Teddy at all... Seems someone must have wanted a different wardrobe and forgot to edit out the teddy scene.
