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: 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 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 the episode starts and credits are still rolling, there are obvious groups of bystanders watching the filming and staring straight at the camera.

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 Sam and Carrie walk, bystanders sneak-in shot to stare at filming.
I heart ny - S4-E18
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.
Anchors away - S5-E1
Revealing mistake: During the scene when the girls are walking down the street, 'strutting' fully dressed up on their way to the Navy party, look behind them in the distance. There appears to be a great crowd of people gathered behind what might be a barrier. These look like people just watching the filming. This is more clear at the very beginning of the scene, when the girls first begin walking down the street. Also, in the TBS web site in the episode guide, there is a photo of this very same scene shot from a different side angle. You can see a definite barrier on the sidewalk to the left, filled with onlookers who are watching the filming. Thus, it's possible that the people in the rear visible in the show, are the same.

Anchors away - S5-E1
Revealing mistake: When Miranda is breast feeding Brady with Carrie in the room, as she pulls down her top, you can see her prosthetic body suit rippling and bunching up.

Revealing mistake: Exactly half a second after it starts to rain at the museum, the street is already soaking wet and covered in puddles.
Anchors away - S5-E1
Revealing mistake: When the cat is playing with the navel, it moves as if it has a life of its own, which is absurd and reveals that there was some wire or mechanism to move it.
Anchors away - S5-E1
Revealing mistake: When Miranda is breastfeeding the baby, there 2 obviously different breasts and bodies: In the close-up (real breasts) the areola is small; but the prosthetic breast has much bigger areolas.
Revealing mistake: When the baby is about to be baptised, it is replaced by a blatant doll: The doll's arm is stretched out (as opposed to the real baby's arms, tucked in his robe), and the doll's hair is very obviously painted.
Cover girl - S5-E4
Revealing mistake: When Samantha is walking down a busy NYC street talking on her cell to Carrie, you can see a man in a blue jacket walking right behind her. The next shot of him; he suddenly pulls out an obvious black camera and takes a photo, aiming it directly at Samantha in front of him. This is apparently not an 'extra', but someone on the street who wanted to take a picture of Kim. There are also a lot of other people in the background walking behind her at this point. But in the next shot of Samantha still walking on the same street and talking on the phone, there are suddenly no people right behind her at all. It's an empty space, and no time has passed for them to have dispersed. They may have cleared the area behind her; because people weren't behaving properly during filming, such as the man taking her picture. This would normally be a continuity error; except that in this case I believe the sudden change in background was due to the guy taking the picture inappropriately, not just a slip in background filming. (00:10:30)
Cover girl - S5-E4
Revealing mistake: When Samantha walks in on Marcus 'servicing' Stanford, the positioning is all wrong. Marcus' head is too high up to be realistic for what is happening. His head is almost up to the level of Stanford's chest. (00:21:20)
Plus one is the loneliest number - S5-E5
Revealing mistake: When Carrie and Berger are walking out of the park, you can see Sarah Jessica Parker's 'baby bulge' noticeably in her abdomen. Her dress doesn't cover it up. (00:06:05)
Plus one is the loneliest number - S5-E5
Revealing mistake: Carrie is wearing a lot cut dress; and Sarah Jessica Parker's pregnancy is again very noticeable at this stage as her chest is filled out, and considerably larger than normal. (00:11:00)
Plus one is the loneliest number - S5-E5
Revealing mistake: The scene where Charlotte is shown sleeping with her new 'plus one' to the next morning was all filmed in entirely one sequence, real time, without any editing. Therefore, Charlotte had to change really quickly into her lingerie, and get into position for the morning shot in a very short period of time. As the camera pans away from Charlotte taking off her clothes at night, there is a mirror on the wall behind her. If you look closely at the mirror, Charlotte appears to fall over quickly, and then suddenly roll/move to the right side and get off of the bed, as if to change into her morning outfit. (00:13:05)
Revealing mistake: When Carrie is watching TV in her apartment, she uses the remote to click off the TV after SNL is over. There is a close-up of the TV screen, reflecting the room in front of it. You can see a round table with a lot of stuff on it, the windows/curtains and desk, and what appears to be a square ottoman of some kind. But Carrie is nowhere in sight, there is just a blank wall reflected where her image should have been. She is directly facing her TV, as shown from the angle of her perspective as she clicks it off. We should be able to see her somewhere within the television reflection, but she isn't there. (00:20:10)
Revealing mistake: After Carrie leaves the hotel bathroom, Samantha is getting out of the tub. In the mirror behind her, you can see that Kim Cattrall (Samantha) is wearing some sort of dark pink undergarment below her waist to hide herself. (00:19:35)
