Naomi Watts attended the ‘Silver Linings Playbook’ event held at the Chateau Marmont on Friday in California.

Clad in a cleanly-designed Stella McCartney Spring 2013 frock, Naomi looks both high fashion and decidedly relaxed at the event.

Barely-there Valentino heels, a Joan Hornig brass cuff and a shimmering Jennifer Fisher necklace complete this breezy ensemble.

The casual pockets and unexpected slit – coupled with the sage tone and heavier fabric – give this dress a pleasant 90s air.

It’s as if Naomi and Stella have taken the best features of the trends favoured by classic 90s teen idols and effectively updated them for the modern era.

It’s a nostalgic feel that’s still fresh.

Is it just us, or does Naomi’s buttery-blonde hair totally remind you of the ‘Rachel’?
