Corrected entry: After Carrie drinks 1 1/2 martinis in Julian's office, she gets extremely drunk. He has to help her walk out of the office, and she is staggering and falling into things. This doesn't seem logical, as Carrie goes out frequently and drinks all the time. Even in the daytime sometimes. She is used to drinking a great deal more than 1 1/2 martinis, and doesn't usually get nearly that drunk. For someone who drinks a considerable amount of alcohol as a normal part of her life, it seems implausible that she would suddenly get stumbling drunk after only one and a half martinis, no matter how strong they are. And it's doubtful Julian would have made them too strong, being during the morning in a major magazine office environment.
Corrected entry: When Carrie spots the Manolo Blahnik black Mary Jane shoes in the Vogue Accessory Closet, there is a close-up of the shoes sitting on the shelf. In the previous episode, it was established that Carrie wears size 7 1/2 in shoes (when she was shopping with Miranda). But when we see the Mary Janes on the shelf, and when Carrie holds them in her hands; they appear to be much larger than size 7 1/2. They look about size 8-10. Yet when Carrie tries them on; she mentions that they 'almost fit', and seems to be having trouble squeezing her feet into them. The implication is that the shoes are actually too tight for her, a smaller size than what she actually wears. Yet instead of looking smaller than size 7 1/2, the shoes are apparently much larger.

Correction: Different shoes fit differently depending on the person. First of all, it is impossible to tell a shoe's size based on camera angle or how it appears on a television screen. Secondly, it's possible they "almost fit" due to being too narrow, not having an adjustable strap, or many other reasons, rather than the assumption that they would be too big.
Correction: Carrie hadn't had any breakfast, and she's a size 2. Nothing implausible about it.
