Hot, hot, HOT! Anne Hathaway leaves little to the imagination in racy see-through dress (LOOK)

With her racy see-through dress, and platinum hair style, Anne Hathaway was clearly delving into her experimental side for Monday evening’s Met Ball.

The stylish star arrived at the occasion with a bleached crop in response to the gala’s PUNK: Chaos to Couture theme.

The star showed off a great deal of cleavage and was a clear departure from the Academy Award-winner’s usually demure looks.

The sequinned head-turner included feathered sleeves and mesh panels, which proved conducive to a slight wardrobe malfunction as she exposed a wayward nipple.

She slicked the sides of her platinum crop and added smokey eyes and lemon yellow nails to the edgy ensemble.

‘I’ve wanted to do it forever! I love it!’ Anne said to MailOnline when asked about her dramatic transformation.

She took the Debbie Harry-inspired leap on Sunday, after being spotted with dark hair at restaurant La Esquina in SoHo on Saturday night.

Her husband, Adam Shulman, complemented his wife by adding ‘guy liner’ to his ensemble, which she appeared to love, saying: ‘I told him to do it. I love it – it makes his eyes pop.’

As the actress entered the event, her Devil Wears Prada co-star Emily Blunt greeted her, squealing: ‘Oh my god! I love it!’

Meanwhile, Nicole Richie arrived at the gala in a white Topshop frock accented by bizarrely frosted tresses.

She contrasted the feminine gown with chunky gold and silver jewellery – including a series of spiked earrings – and oxblood lipstick.

But it was the Simple Life star’s blue-tinged locks that became the focus of her ensemble as she posed on the event’s red carpet.

The unsightly hairstyle substantially aged the young mother of two.

Nicki Minaj, Alicia Keyes, and Zachary Quinto also indulged in eccentric hairstyles with Nicki attracting attention with a wig of high blonde frizzy curls.
