Busty Kim Kardashian flaunts her TINY waist in a figure-hugging purple gown as she looks slimmer than ever at little sister Kylie's birthday celebrations

She's always been proud of her hourglass curves. 

But Kim Kardashian's svelte physique was looking trimmer than ever as she joined her family to celebrate Kylie Jenner's 20th birthday in Los Angeles on Wednesday.

Whilst the night may have been all about her little sister, Kim, 36, ensured she'd still turn heads as she slipped into a figure-hugging purple gown for Kendrick Lamar's concert at the Staples Center.

Slay in navy satin like Kris Jenner

She has good genes! Kris Jenner hardly looks like she could be the mother of her famous brood. For Kylie's big day, she wore a navy satin slip dress, how very current!, with a Gucci jacket in retro contrasting print, top handle bag and black strappy sandals.

The famous mom-ager usually dresses more conservatively than her style setting girls, so it was refreshing to see her in an of-the-moment slip dress style, but as always she kept things professional by covering up her shoulders with the overcoat.

The good news is that Kris's dress is available online and will only set you back $375. Buy it here at Bloomingdale's!

Featuring a scooping neckline, the glittering gown offered a look at her ample cleavage, whilst it cinched in at her slender waist and skimmed over her famously bodacious behind.  

Ensuring all eyes would be on her fabulous figure, Kim opted for a neutral make-up palette that highlighted her flawless features. 

She finished off the look by styling her raven locks in a slick centre parting that framed her pretty face.

Kim's tiny figure comes amid reports she is expecting her third child with Kanye West - this time through a surrogate. 

Following reports that the pair would pay $113,850 (£87,228) for a surrogacy deal, UsWeekly have alleged they have now hired a surrogate who is 'three months pregnant'.

Kim's outing came as Kylie Jenner officially kicked off her 20th birthday festivities, attending Kendrick Lamar's concert for the third time in a week.

As well as by Kim, the birthday girl was joined backstage at Staples Center by her momager Kris, big sister Kendall, and half-sister Khloé Kardashian.

Capturing much of the action was 33-year-old Khloé, who will celebrate her first anniversary with Cleveland Cavaliers center Tristan Thompson next month. 

For her special night, Kylie dressed down in a white tank mini-dress beneath a matching hoodie and sneakers selected by stylist Jill Jacobs.

The Keeping Up with the Kardashians stunner - whose BFF Jordyn Woods never left her side - also sported waist-length hair extensions by Tokyo Stylez as she treated herself to a bag of Dippin' Dots. 

Though her sweet choice certainly wasn't reflective of the glamour inside her bash, as Snapchat posts revealed that there was also an ice sculpture of Kylie's hourglass figure, which her included her famous derriere.
