Tonight's the launch of Pat Field's new line for Payless - her cheap-and-shiny shoes are called Sake, Sushi, and Tempura, so don't get excited if you received an invitation, as it's not the menu you're looking at, just the heels. The party happens in her Bowery headquarters, and since her name's on the invitation (and the expensively wrangled collaboration), most expect her to be there. The only issue? Sex and the City is scheduled to film tonight on Mercer Street at 8 pm. We know because they've papered our entire neighborhood with signs that say so. And if Patricia is the costume doyenne of Carrie and Company, she's probably needed in the Manolo trailer. Where will Patricia Field be tonight? Only time - and the paparazzi - will tell. But if you're a huge fan of hers, just park yourself somewhere in Soho and look out for the neon gorgeousness of her hair, and you'll spot her soon enough.
