Trivia: During the scenes in the department store, they were filming at the real Barneys. Also, the blindfold that Charlotte is wearing is from Burberry. The show asked if they had Burberry blindfolds, and they didn't make them at that time. But they then tailor-made a Burberry blindfold, just for Charlotte to use in these scenes.
Trivia: Concerning the entire Wall Street/Stock Market scenes; Sex And The City was the very first production to film in the New York Stock Exchange since the movie Wall Street. They filmed these scenes at the actual NYSE. Because it was after 9-11, every piece of camera equipment, prop, costume, etc. had to be sniffed by bomb-sniffing dogs. This was the very first non-official event that was let into the Stock Market after 9-11. Every extra that you can see on the Stock Market floor was an actual trader. Also, Sex And The City got to open the real Stock Market, on the day the show premiered.
Trivia: Carrie is carrying a small bunch of violets in this Parisian montage. What is interesting is that in France, traditionally, violets are the flowers that the husband gives his wife when he has disappointed her, or they have had a fight. Symbolically, the violets that Carrie bought for herself represent that she is continually disappointed by Aleksandr.
Trivia: When Trey and Charlotte are viewed through the Tiffany window, it isn't the actual window. Tiffany would not allow cameras to film inside their store, so the show built a fake Tiffany window. But Tiffany sent their dressers to dress the window, to make it appear authentic to the real thing.
Trivia: During this scene, Carrie states to the other girls, "If you want to do your patriotic duty as New York women, you will come shopping with me right now and throw some much needed money Downtown". According to the commentary, this is possibly the only direct reference to New York City and 9-11 in the entire episode. Downtown NYC was very hurt by the World Trade Towers disaster, and the show thought that Carrie's character would be doing her part, which includes shopping.
Trivia: When Carrie is typing on her computer, she changes the question mark to a period. The moment she does this, there is no more computer typing shown in the entire series, until the very last moment in the final montage. This was done to signify that Carrie had stopped questioning her life.
Trivia: During this scene when Richard and Samantha are dancing by the pool, you can see the NYC skyline behind them. The World Trade Towers were visible right between them, when this was filmed. They were later taken out, and this was the only time in the entire series that anything was digitally removed from the show. They removed the World Trade Towers for two reasons: One; they would have changed the entire tone of the scene and made it sad and tragic. Two; when the show actually aired the World Trade Towers had already been destroyed. They wanted the show to appear current, as if it was happening now and not in the past. If they had left the World Trade Towers in the shot, it would have looked like it was filmed in the past.
