The actress - who reprises her role as glamorous journalist Carrie Bradshaw in the movie sequel - admits she changed outfits so many times, more than 10 were lost to the cutting room floor.
She said: "I think I have about 48. We started off with 60 and I think scenes were cut and scenes didn't make it. So I think between scenes being cut prior to shooting and us not being able to find a good enough reason to change clothes on camera, which is what I would do if they would let me, I think we end up in high 40s."
Despite showcasing many designer creations in the film, the actress' favourite piece she wore was a petticoat.
She told US TV show 'Access Hollywood': "My favourite is when Carrie runs into Aidan in the Souk and I'm wearing an old vintage J'Adore Dior T-shirt and the underpinnings of a Zac Posen dress. Not the dress itself, but rather the petticoat and a pair of Manolos that were made for the movie."
