Continuity: Carrie, Samantha and Miranda are at the opening of Steve and Aidan's bar. Carrie lifts her hair off her neck with her right arm, but then in the next shot, she is lowering her left arm.

Factual error: A motherboard crash would not result in Carrie's losing all of the files on her hard drive. The hard drive can be removed and placed into a peripheral, which can then be accessed by plugging it into a new computer.

Other: When Samantha first has sex with the positions expert, they are supposed to be having sex at a moment where he flips her over but she isn't close enough to him to hide the fact that he isn't inside her.

Continuity: When Carrie is startled by the squirrel and tosses the pie crust onto the counter, the camera cuts to her clasping her legs where she burnt them. In the next shot of the counter the pie crust has vanished; then in the next shot of it, the crust has returned.

Continuity: Miranda and Steve are sitting on Miranda's sofa eating Chinese food and discussing Steve's cancer surgery. There's a close-up shot of Steve, who is wearing eyeglasses. The shot cuts to a close-up of Miranda and then back to Steve, who is now not wearing any glasses. He is not holding them, nor are they on the coffee table.

Continuity: In the restaurant with Big and Carrie, Big's either holding the stem of his wine glass, or holding it above the stem between shots. There isn't any time for him to switch the position of his hand between shots.

Continuity: In Series 4, episode "Coulda, Woulda, Shoulda" Carrie is sitting at her laptop eating a blue ice pop. She takes a bite from the top then holds the stick with the rest of the ice pop in between her teeth while she types on the laptop, we see a shot of the screen. When we go back to Carrie she is eating the rest of the ice pop which is impossible because just 2 seconds before it was still attached to the stick. She didn't have time to bite it off the stick because she was using both her hands to type.

Continuity: At the bar "Trade" Charlotte is having tape on her upper body in one shot, but it disappears a second later when she sees Anthony. She has no time to take it off.

Deliberate "mistake": At the end when Carrie and Aidan are lying in bed, she is watching her snow globe and the glitter inside is moving around. That is impossible to happen without it being shaken up first. The swirling snow globe is meant to be significant but it's still a mistake.

Plot hole: After Charlotte gives Carrie her engagement ring for the down payment on her co-op, wouldn't Carrie still have to qualify for a mortgage loan? It would have made more sense if she had asked one of her more well-to-do friends to co-sign the loan for her. It wouldn't cost them anything (unless Carrie defaulted, of course) and it would explain how she managed to buy a New York co-op with $1600 worth of assets.

Continuity: When Carrie and the Vogue editor are drinking martinis in his office, the level of liquor in their glasses changes from shot to shot.
