Do my assets look big in this? Kim Kardashian checks out her famous curves as she shops for the perfect 30th birthday dress

Do my assets look big in this? Kim Kardashian checks out her famous curves as she shops for the perfect 30th birthday dress - When shopping for the perfect outfit for a milestone birthday celebration, most women would opt for a dress that doesn't make their bottom look big.

But not Kim Kardashian, who made sure that her curvy derriere was the main attraction as she shopped for a dress for her 30th birthday.

The reality TV star was snapped in Las Vegas, checking out her curves in a white Hervé Léger dress in a dressing room mirror.

And she made sure that the dress fitted snugly round her bottom and and bosom as she admired herself in the mirror.

But despite the dress fitting the star in all the right places, she settled for a very short and very tight metallic silver dress that did exactly the same thing.

Kim, who turns 30 next Thursday, was in the Nevada city to celebrate her milestone birthday when she and her sister Kourtney hit the shops.

They visited a series of high-end stores hours before heading to a party in her honour at the popular TAO nightclub.

Wearing a similar black and white outfit to the one she travelled to Vegas in the day before, Kim visited the pool at the Venetian hotel and was greeted by a crowd of fans and photographers.

Later she and Kourtney enjoyed lunch with friends around the pool in one of the hotel's private cabanas.

The Kardashian sisters' celebrity continues to grow as they take on more projects, but one thing Kim says she regrets is posing for Playboy in 2007.

In an interview with Harper's Bazaar she recently said she was 'sorry' she bared all in a raunchy cover story for the men's magazine.

Despite her penchant for living her life in the spotlight, she claims that what you see isn't really what you get.

She told the latest issue of W magazine: 'I'm not a drinker, and when I'm up on the table dancing, it's for the picture'.

'Then I sit right back down. I play into the perception of me, but it's not really me. And the show reveals that.'

Kim's entire family were all at her bash last night, the night appeared to go smoothly - unlike her last birthday.

Last year Scott Disick - Kim's sister Kourtney's partner - drank too much, went on a violent rampage and ruined Kim's 29th birthday celebration.
