Revealing mistake: During the opening credits, a shot of Hepburn looking into Tiffany's window from inside the store has her taking a sip of coffee. The cup is tilted and the level of the coffee is also tilted, which suggests that the cup simply had a brown coffee-colored insert so that no liquid would be spilled. (00:01:41)
Continuity mistake: In the scene at the apartment, Holly is tossing lettuce in a bowl. Behind her is the stove top, where a pot is resting on an unlit hob, and a yellow bowl is to the right of this. In the next cut, we see a flame burning under what appears to be a different pot and the yellow bowl has moved closer to the said pot.
Answer: Holly is referring to the fact that people often ask others in the room "Will you turn around?" when they are dressing or in the nude, so the person cannot see them naked. She is simply stating she thinks it is odd that the second person is always asked to turn around, when the person herself could turn around.
