Friday night saw the world premiere of Whitney Sudler-Smith’s documentary “Ultrasuede: In Search of Halston”.

Sarah Jessica Parker, who recently joined Halston Heritage as president and chief creative officer arrived on the red carpet wearing a Stella McCartney Spring 2009 look.

I guess wearing Halston would’ve been too obvious.

Her ensemble included a stand-out stunning sequin ombre tank dress, paired with a blue cashmere boyfriend sweater.

Gold Brian Atwood strappy sandals and a cross-over Lanvin bag completed the look.

I still wonder why people wear cross-over bags on the red carpet as they can be so unflattering.
