Emma Watson Dazzles In White. Is This Her Best Noah Look Yet?

The actress continues her stunning style tour, this time turning heads at the London premiere of her upcoming film

Emma Watson has been treating us to one gorgeous red carpet look after another as she promotes her upcoming film Noah.

But we're very pleased to report that she saved the best look for her London fans.

The 23-year-old British actress made a stunning arrival for the London Noah premiere on Monday night. She chose a white Ralph Lauren Collection halter dress that perfectly showcased her trim figure.

Emma paired the dress with a simple pair of pointy-toed courts - which, thanks to the gown's sexy slit, were in full view when she walked. She accessorised the look with two matching silver Jennifer Fisher cuffs.

In the Biblical story, Emma plays an orphan - but she may soon be playing a mermaid.

Rumours have been flying that she'll be the one taking on the role of Ariel in Sofia Coppola's live-action adaptation of The Little Mermaid. Emma addressed the gossip on the red carpet Monday.

'I'd be really intrigued to read a script,' she told The Telegraph.

The actress also commented on the casting rumours at the New York City premiere last week. 'I actually dressed up as Ariel for my fifth birthday,' she joked. 'I mean I'd have to read it first. I love Sofia so much.'

See? She already has experience wearing the mermaid tail...
