Continuity: At the beginning of every show we see Carrie walking down the street and she gets splashed by the bus. First the bus has people on it, then in the next shot they all disappear.

Continuity: In the episode "Secret Sex," Samantha and Carrie are hanging Carrie's poster in her apartment. In one shot, the whole poster is pinned to the wall and in the next shot, the bottom left part of the poster is curling up. After another shot of Samantha, the poster is pinned perfectly to the wall again.

Deliberate "mistake": In the scene at the beach party, when Carrie brings everyone beers, Miranda says "There's so much foam, I could ski on the head," but the cups are tipped toward camera and you can see there's no foam at all.

Continuity: In season 1 "Valley of the 20-Something Guys," Carrie receives a phone call from Samantha and her voice over says she needs her morning Marlboro Light, however, when she picks up her pack of cigarettes, you can see that it is a pack of Merits.

Continuity: While talking to her protege, Carrie stubs out her cigarette twice, right before she runs into Big and Natasha.
