Sex and the City is a American romantic comedy film adaptation of the HBO comedy series of the same name. After moving in together in an impossibly beautiful New York apartment, Carrie Bradshaw and Mr. Big make a rather arbitrary decision to get married.
The wedding itself proves to be anything but a hasty affair--the guest list quickly blooms from 75 to 200 guests, and Carrie's simple, label-less wedding gown gives way to an enormous creation that makes her look like a gigantic cream puff.
An upcoming photo spread in Vogue puts the event--which will take place at the New York Public Library--squarely in the public eye. Meanwhile, Carrie's girlfriends--Samantha, the sexpot; Charlotte, the sweet naïf; and Miranda, the rigid perfectionist--could not be happier. At least, they couldn't be happier for Carrie.
Charlotte still has the unrealized hope of getting pregnant. Samantha is finding a loving, committed relationship more grueling than she could have imagined. Miranda unwittingly lets her own unhappiness--created when Steve admits to cheating on her just once--spoil Carrie's.
After a heated encounter with Steve, she happens to spot Mr. Big and tells him he's crazy to get married. She's really only thinking of her own marriage. But her angry remark gets Mr. Big to thinking.
Mr. Big and Carrie buy a magnificent penthouse in Manhattan and they decide to get married. Enid Frick invites Carrie to take pictures for a special edition of Vogue about marriage of women of forty and something years. During the preparation, Carrie raises the guest list from seventy-five to two hundred guests, and a simple wedding dress to a fashionable Vivienne Westwood, intimidating Mr. Big in his third wedding.
Meanwhile Miranda has no sex with Steve and he confesses that he had had one night stand with a woman. On the eve of the wedding, in the rehearsal dinner, the upset Miranda tells Mr. Big that marriage ruins everything. On the next day, the scared Mr. Big calls off the wedding leaving Carrie in the church.
Carrie feels humiliated and depressed and Samantha, Miranda and Charlotte decide to travel to Mexico with Carrie to the hotel where she was supposed to spend her honeymoon.
When Carries returns, she hires the assistant Louise to help her to organize her life. When Miranda discloses what she told to Mr. Big to Carrie in the rehearsal dinner, their friendship is shaken.
