Revealing mistake: When the gardener hands Charlotte the rose, he is supposedly picking it out of some rose bushes he is in the process of planting. He even makes a motion as if 'picking' it from the bunch. But when he hands the single long stem rose to Charlotte; it's obvious that this rose has already been cut, and is missing the lower leaves.

Continuity mistake: When Carrie and Mr. Big are having their affair in the 3rd hotel; it is located on 56th & 8th, and is described as being a 'seedy location'. When you see the inside of the hotel room, it is obviously a very cheap, tacky hotel. But later in the episode when Carrie and Mr. Big are in the lobby of this same hotel on 56th & 8th (verified in voice over); it is obviously the lobby of a much nicer, elegant, more expensive hotel. (00:02:05 - 00:19:30)
Plot hole: When Carrie calls the girls from Aleksandr's couch, she is wearing one outfit. In voice-over, she says she stayed at his apartment for 4 days. But then when she finally arrives home, she is wearing a completely different outfit. How would she have so many clothes to wear, when she didn't expect to be away from home for 4 days? She wasn't carrying any luggage or other clothing with her when she came home, either. (00:09:25)
Visible crew/equipment: When Carrie is entering the NYSE, she has to go through a metal screener. When the security guards are using the wands on her, she spreads her arms, and you can then see some sort of horizontal line or wire sticking out from under her dress, around the waist. There also appears to be something above the wire, showing through the material. She seems to be wearing some sort of contraption under her dress, and when she moves, the entire object moves loosely. Possibly this is her microphone and attached wire? (00:02:40)
Continuity mistake: When Carrie and Aiden are arguing out on the street in front of her apartment, there is a shot of her holding the leash for Pete the dog in both hands. But suddenly as she is yelling at Aiden, you can see her throw both her hands up in the air and touch her head. She is not holding the leash at all. Then seconds later; there is a shot of her legs as Pete is running off, dragging the leash from her body and waist as if she is still holding it. (00:24:30)
Plot hole: After Carrie has her strenuous night with the 'fling', she is shown lying flat on her apartment floor in the morning, as if unable to move very much. But there is a cup of coffee next to her, obviously bought from somewhere in the city. Carrie is so disabled from her injury that when she reaches the church, she is hunched over, can barely walk, and Stanford has to help her along. She is affected a great deal from her 'sex sprain' during the entire wedding. So how is it that she was able to get up and go buy a cup of coffee outside of her apartment in the morning, when she was so injured she couldn't do much but lie flat on the floor when Charlotte called her? It doesn't seem likely that Carrie would have gone to all that effort to go out and buy coffee, when she is so immobile. She wasn't able to get around well enough for a small errand. (00:17:15)
Character mistake: When Carrie is describing the younger guy she is dating, she claims he is the creator of an Internet magazine 'that she still wasn't able to find on her computer'; meaning she had searched the Internet for it. But as we learn later in the series, right before she gets back together with Aidan for the second time; she doesn't have the Internet on her computer until then. The girls talk her into getting it, in order to email Aidan. So there was no way she could have searched for the other guy's Internet magazine on her computer, as it was an older Mac laptop and not likely to have search engines without Internet access. She was only using the hard drive at that time.
