Black is usually a cop out when it comes to making a style statement.

But Kim and Khloe Kardashian turned the concept on its head today with their sheer ensembles.

Spotted outside of her New York hotel, 31-year-old Kim stole the show in a see-through blouse, with ruffled neck detail and polka dots on the sleeves, which brazenly exposed her bra beneath.

She polished off the risqué look, more suited to a red carpet than day attire, with a leather pencil skirt and ankle-cuff heels, gelling her hair back into a slick ponytail.

Khloe looked chic in a low-cut dress and sky-high hemline, masked only by an outer layer of chiffon.

The 28-year-old, currently vying for The X Factor USA hosting job, revealed on Good Morning America yesterday that she never anticipated how difficult it would be to conceive a child.

She revealed: 'My mum [Kris Jenner] has so many kids, and Kourtney pops them out like a PEZ dispenser, so you think it's easy.'

But Khloe, who is seeking fertility treatment with husband Lamar Odom, added: 'It was really hard to show what I was going through [on her E! reality show].

'I feel like I'm helping a lot of people, but I'm still figuring it out for myself. It's trial and error. You get put on hormones and see if they work, and if they don't, you move to the next step.'

Meanwhile, Kim has come forward to defend herself after an interview in The Guardian claimed she compared the dramas of her short-lived marriage to Kris Humphries to that of a cancer sufferer.

She blogged: 'I want to clear something up for you all, because it seems that something I said has been taken way out of context...

'In a recent magazine interview, I told of how I had called a female fan who was battling cancer, and she told me how she had watched the show and seen how I had faced my own struggles, and had been inspired by how I had found the courage to change a situation that was making me unhappy.

'She told me... a lot of friends had deserted her, which is something I said I could relate to.

'In no way was I comparing my own experiences to that of a cancer patient. I was merely talking about how there are times in your life... when you find out who loves you enough to stand by you... '

The girls have been busy plugging their latest range for fashion line Kardashian Kollection, hitting Sears in Yonkers today for a meet-and-greet with fans.
