ALL eyes will be on style queen Sarah Jessica Parker when she graces Flemington for Crown Oaks Day today.

The Sex and the City star drew gasps from an appreciative audience when she made a special appearance at the Crown Oaks Lunch yesterday.

Sporting a chic Chanel tweed dress and spectacular Philip Treacy headpiece, the petite actor lived up to her reputation as a style guru.

Gracious and affable, she didn't disappoint the 1500 mostly female guests.

Her sculptured black hat, more like a piece of art than mere millinery, was a hit.

Parker said she had not settled on her race-day outfit.

"I will say I hope I live up to the history and the glamour and the tradition that has been so well established," she said.

Parker is in Melbourne to promote her new film, I Don't Know How She Does It, which premiered at Crown last night.
