Kim Kardashian took to Instagram on Monday to show off her ultra-trim waistline in a series of throwback pictures from her birthday celebration last month.

The beauty, 42, was decked out in Dolce & Gabbana and flaunted her taut torso in a silver metallic bra top with matching sparkly wide-leg trousers.

Standing in the aisle of her sister Kylie Jenner‘s private jet, with her right hand on the ceiling, the stunner displayed her toned figure while her jewel-encrusted cross choker glimmered around her neck.

In the 10-image-carousel shared with her 333M followers, the entrepreneur looked beautiful as her long platinum blonde hair fell naturally with a part in the middle.

Keeping with shimmery, smoky eye makeup beneath defined brows, she opted for long lashes and a nude/pink lip.

The mother-of-four captioned the post, ‘VEGAS BABY…ALMOST It’s all about the journey anyway.’ 

The reality TV star showed off her disappearing curves and chiseled abs as she  embarked on a trip to Vegas with close friends and family for her birthday.

Upon their return to Los Angeles, the beauties took their canceled plans in stride and brought the party to a local In-n-out burger where they chowed down on LA’s best burgers and fries.
