Sheer Daring! Kim Kardashian Does See-Through Cream Fishnet Top For Mario Testino Exhibition

Well we thought we'd seen Kim Kardashian's cleavage in all its glory before (remember that Mademoiselle C premiere dress?) but, apparently, we hadn't.

Because Kim was REALLY showing off 'the girls' at a private viewing of Mario Testino's Alta Moda exhibition in New York on Monday night.

The new mum stepped out in a sheer fishnet-inspired top , leaving her curves stealing Mario's limelight. The high neck and long sleeves, as well as the gorgeous fitted cream skirt, kept the look chic, however, and it's fair to say Kim looked quite stunning.

She paired the look with a sleek ponytail and goth-glam berry lips, as well as her favourite Tom Ford chain-embellished gold heels.

Kim was joined at the bash by her model sister, Kendall, who looked super-stylish in a fuzzy jumper, check-print trousers and black stilettos.

Both sisters looked amazing, but Kim's outfit was a bit of show-stealer, wasn't it?
