Emma Watson lit up the red carpet at the Noah premiere in New York in an unreal Oscar de la Renta gown.

The actress is always notable for her fashion-forward looks, but here she's gone for something classic, with a timeless, Old Hollywood feel.

There are so many things to love about this dress - the chic three-quarter length sleeves, deep plunging back, gathered skirt and waterfall hemline that reveals her gorgeous pointed suede Louboutins.

She kept the ensemble from looking too grown-up, she is just 23 after all, by going for a matte, bright orange lip and beautiful ear cuff by Ana Khouri.

This make-up look should be easy to recreate at home too, with a defined brow, lightly shadowed eyes providing the backdrop for the dramatic lipstick.

Top marks!
