LONDON, Sep 16, 2002/ --- Internationally respected milliner Philip Treacy Thursday cancelled his New York Fashion Week show, scheduled for Saturday September 21, after a slip-up that resulted in his show clashing with Jeremy Scott's presentation.

The show, which was due to take place at the W Hotel in Times Square, was booked, paid for, and planned right down to the last detail.

Naomi Campbell was due to model, Deborah Harry and Grace Jones had RSVP'd, and a fleet of Jags, Mercedes and Cadillacs were ready to ferry the models in to begin the show.

Even a crystal-studded red carpet had been ordered to serve as a catwalk for the Oscar-themed event, which was sure to be a glamourous highlight of the week.

"Having agreed with 7th on Sixth that we were to have the Saturday evening slot, we found when the schedule was released that our show clashed with Jeremy Scott's," says Pat Marsh, Treacy's business partner.

"Philip doesn't want press and buyers to have to make a choice between two designers. We want the optimum turnout. We did the professional thing by negotiating our slot in advance, and we are doing the professional thing by pulling out. We do things perfectly or not at all. It is a real blow. Philip is deeply upset."

The Treacy team had 120 hotel rooms booked, 22 flights confirmed, and had arranged police permits with the NYPD to hold the show at the entrance to the W Hotel.

"We have worked extremely hard for weeks to prepare our event, I can't begin to estimate how much money we have lost," said Marsh.

According to Marsh 7th on Sixth is "deeply upset and embarrassed" at the situation.

At press time, no one there was authorized to comment on the matter.

Treacy is the best-known milliner in the world.

His hats are masterpieces, and he shows them only once a year at events that are as much social gatherings as they are fashion presentations.

He is currently the subject of a show at London's Design Museum with British style maven Isabella Blow called "When Philip met Isabella."

His couture clients include Valentino and Chanel.

Treacy's latest collection was to include one-off hats using Andy Warhol artwork.

The designer had been given permission to use the Coca Cola, Campbell Soup and Marilyn Monroe screenprints by the Warhol Foundation.
