Revealing mistake: When Charlotte is putting her diamond ring on in her apartment, there is a close-up shot of it. It is a large, circular diamond on a simple golden band. This is not the same diamond engagement ring she has been wearing previously in the series. That ring had two parallel silver bands, and the diamond looked slightly different. (00:10:10)
Revealing mistake: When Aidan and Carrie shower, some sort of screen or towel briefly appears by their waists to add for some privacy and avoid their private body parts (or any garment covering them) being exposed.

Revealing mistake: At the end of this episode when Carrie is walking away from Mr. Big's apartment; she notices an Autumn leaf, and follows it with her eyes as it floats down to the ground. However, this leaf is actually digital and not real. Sarah Jessica Parker had to pretend to be staring at a leaf that wasn't there while filming; and if you watch her gaze carefully, it doesn't always follow the path of the leaf. She looks down too soon, before the leaf has a chance to float down that far. (00:29:40)
Revealing mistake: When Samantha is surprised at Richard's apartment by his assistant, she quickly throws her towel around herself to cover up. But the towel rides up too far, and you can see that Kim Cattrall is wearing tan or nude colored underwear. Soon after that, Samantha makes a comment to the assistant that implies she was nude under the towel. So the panties were probably for the benefit of the actress, to protect her modesty below the waist. (00:21:40)

Revealing mistake: When Charlotte arrives at Carrie's apartment to pick her up, Carrie is in the shower. As Charlotte walks towards the bathroom, there is a clear shot of Carrie showering.

Revealing mistake: Just after Big has left NY for good, Carrie leaves his apartment and is walking down the street. A leaf (that another mistake pointed out was digital as it was falling to the ground) is lying on the sidewalk. Carrie picks it up, but it is obviously an artificial one made from plastic and fabric.
Ghost town - S4-E5
Revealing mistake: When Samantha and Maria are in the bath tub arguing; Samantha decides to leave, and suddenly gets up out of the water. She is not wearing anything from the waist up; but if you look closely just at the end of the scene, you can briefly see that Kim Cattrall is actually wearing some sort of minimal dark undergarment below her waist to cover herself. You can see a black strip of material across her hips. (00:11:20)
