Running with scissors - S3-E11
Continuity mistake: When Carrie is in Big's kitchen, and hears Natasha come home, she tries to leave in a hurry. She puts on her blue levi jacket, so it's about halfway on with her left arm in the sleeve. But in the next shot of her, Carrie is suddenly wearing only her pink bra and carrying the blue jacket. As she unlocks the door and starts running down the stairs, she throws on the blue levi jacket for the second time. (00:25:15)
