Naomi Watts and Coco Rocha show off their svelte figures in elegant black and white at New York jewellery store opening

They come from vastly different worlds and have a twenty year age difference between them.

But Coco Rocha and Naomi Watts both showed that simplicity is the key when it comes to a chic look.

The 46-year-old British-born actress and 26-year-old Canadian model were two of the stars in attendance at the Nirav Modi jewellery store opening in New York City on Tuesday night.

As the lovely ladies wanted to make sure their intricate bling was what would be grabbing the attention, they both opted to wear black and white ensembles for the occasion.

Naomi looked elegant in a black midi dress featuring a zipper down the middle and flared sleeves.

The King Kong actress matched the look with a pair of strappy black heels and patterned clutch.
