Kylie Jenner dares to bare some skin in clingy crop top as she attends Kim's 35th birthday party with boyfriend Tyga 

She wasn't the one being feted but Kylie Jenner certainly made sure she made a lasting impression anyway.

The 18-year-old reality star stood out in an all black and revealing ensemble as she and boyfriend Tyga hit up Kim Kardashian's surprise 35th birthday party at Cinepolis in Thousand Oaks, California on Wednesday.

Kylie was clad in a long coat with trailing sleeves and skintight leggings, but it was the tiny crop top and the toned waistline it exposed that stole the gazes.

She added black suede lace-up boots with spike heels, a chic black handbag and extra large shades that rivaled the ones favoured by the late Jackie Kennedy Onassis.

The youngest member of the famous clan kept her cool as she sauntered to her sister's bash at the luxury cinema and dining complex alongside her rapper beau.

Her features were composed and immobile, but then again she has spent years watching Kim perfect the same expression.

Stand out in Kendall's Tom Ford patchwork sandals

After opening the Balmain x H&M fashion now in New York, jetsetter Kendall Jenner rushed back to LA to help her sister Kim celebrate her 35th birthday.

Ever the supermodel, she flaunted her slender figure in a ripped t-shirt and bodycon skirt along with a pair of Tom Ford sandals.

The block heel stunners were very popular this past season with Kim and Khloe Kardashian and Mary J. Blige each donning a pair. And with the luxe leather and velvet finish and trendy lace up detail, we can see exactly why this shoe is so appealing.

Kendall's exact version is all sold out, but click right to get a similar pair at Net-A-Porter. And if you want the look at a price that won't break the bank, head south to the carousel for more options.

We're partial to L.A.M.B.'s strappy number at Amazon. Style them with an LBD or cropped pants and you won't go amiss.

While Kylie opted for the thoroughly modern sexy look, Tyga went for a black baseball cap, black jeans, black jacket and a basketball-themed T-shirt.

Kylie - and sister Kendall - had just arrived home to Los Angeles following the Balmain X H&M fashion show in New York City. 

It seemed that everyone was in need of some cheering after the rough week they've had as a result of Lamar Odom's health ordeal.

The former NBA player slipped into a coma following a drug and alcohol-fueled bender at a legal Nevada brothel last week.

Now out of the coma, Lamar has been transferred to a Los Angeles-area hospital to continue treatment.   

Regardless of the strain, Kanye West wanted to give his heavily pregnant wife a surprise birthday she wouldn't soon forget.

A plaque of white roses were brought inside the venue along with clusters of big white balloons.

Also seen arriving to the party were momager Kris Jenner and her boyfriend Corey Gamble, Kendall Jenner and Kourtney Kardashian.

While Kris and Kourtney followed Kylie's example by wearing black outfits, Kendall deviated from the norm in mostly white including a tied T-shirt and slim skirt along with thick-strapped black high heels.

The birthday woman herself, Kim, opted for a skintight nude midi-dress that outlined her big pregnancy bump and everything else.

Kim threw on a matching flesh-toned coat and gladiator-style beige heels for added effect.
