Kim Kardashian flaunts her gym-honed 116 pound hourglass frame with sister Kourtney at LACMA Art + Film Gala

They dressed up as Victoria's Secret Angels with their other three sisters for Halloween earlier in the week. 

But Kim and Kourtney Kardashian opted for a one-on-one sister date on Saturday night.

Attending the LACMA Art + Film Gala presented by Gucci, the 38 and 39-year-olds were a vision in the black ensembles. 

Kim has showcased her ample cleavage and enviable hourglass physique in a Tom Ford gown for the evening event. 

The satin design was perfectly hugged her curves and featured a longer pleated design on one side. 

She teamed the look with open-toed heels and accessorized with a cross choker and a carry bag of the same color. 

Kim added extensions to her dark locks for the Gala. 

Her tresses were styled into loose waves and effortlessly flowed over her shoulders with a center path. 

The KKW Beauty entrepreneur kept her glam dramatic with a darkly lined eye and heavy lash extensions. 

Getting her makeup done by sister Kylie Jenner's artist, Ariel, he finished the look with subtly contoured cheeks, a bold brow and overlined nude matte lip.

Sister Kourtney also put on a head-turning and jaw-dropping display.

The eldest Kardashian opted for a straight cut halter neck that gave a modest glimpse of her surgically enhanced breasts. 

Her floor-length dress featured a sexy open back and hugged her gym-honed physique.  

Kourtney kept her accessories minimal with a handheld clutch and a pair of stud earrings. 

The mom-of-three styled her dark Armenian tresses straight and into a half-up-half-down style. 

Kourtney's glam was kept much more simple with a bronzed and contoured complexion that was complete with a light sweep of blush. 

She sported a subtle smokey burgundy eye and had a nude semi-matte lip. 

Kim and Kourtney both took to social media to share a sneak peek of their ensembles with their fans.  

The duo is at LACMA in Los Angeles to attend the Art + Film Gala, honoring influential American photographer Catherine Opie and Academy Award-winning filmmaker Guillermo del Toro. 

Leonardo DiCaprio will be the co-chair the event for the eighth consecutive year.
