The ladies were dazzling, the fashions were sleek and sexy...What else would you expect at the World Premiere of Sex and the City?

But what was Sarah Jessica Parker wearing on her head?

The New York Post calls her "The Mad Hatter" and TV hosts didn't know what to make of it, calling it an "awful hat" and "the dumbest-looking hat ever."

INSIDE EDITION learned that the hat was made by famed British hat designer Philip Treacy.  He used turkey, peacock, and chicken feathers, and silk flowers.  It was all handmade, a one-of-a-kind creation that measured fifteen inches tall.

The other stars played it a little safer.  Kim Cattrall wore an off-the-shoulder Vivienne Westwood creation, Kristin Davis wore vintage Guy Laroche, and Cynthia Nixon dared to bare in a floor-length Calvin Klein gown.

The London fans screamed their approval...but why was the premiere in London?  After all, the TV series and the movie are set in New York City.  Cynthia Nixon explained: "We're kind of having a smallish premiere [in London] and a smallish premiere in Berlin to build up to the big New York premiere."

And the first reviews for the much-anticipated movie are in.  They're mostly positive.  The London Telegraph wrote that it was "coarse [...] materialistic [...] just as we hoped and expected it would be."  But a reviewer for the Times of London gave the movie two stars out of five.

Promotion for the movie is in over-drive.  Sarah Jessica Parker made the cover of the latest issue of Vogue magazine, inside there are stylish shots of Ms. Parker and co-star Chris Noth, taken by famed photographer Annie Leibovitz.

Thankfully, Parker left that hat at home!
