Kim Kardashian almost busts out of barely

KIM Kardashian has flashed major cleavage in a black scarf top as she celebrates her friend Riccardo Tisci's birthday.

The Kardashians star has been showing off her fit figure this summer with sexy pics online.

Now Kim, 42, has nearly suffered a major wardrobe malfunction while wearing a revealing top in a throwback photo.

The reality star took to her Instagram Stories on Tuesday night to share various snaps in honor of Italian fashion designer Riccardo's 49th birthday.

The TV personality posted an old picture from events in her early days of fame alongside the Burberry chief creative officer, her sister Kendall, and family friend Justin Bieber.

In another photo, Kim posed next to her mom Kris Jenner, 67, and her longtime designer friend as the group showed off their tanned skin in all black attire.

The Skims founder included snaps from a cover shoot with Riccardo while she was pregnant with her now seven-year-old son Saint and a video of the designer styling her for another shoot with Givenchy.

One extra sultry throwback pic showed the Hulu star flashing major cleavage in a plunging black scarf top paired with a long skirt.

At the time, Kim was extra curvy, showing off full glam makeup and a honey blonde hair style.

In the background, Riccardo could be seen dressed in a tuxedo and smoking a cigarette.

The mother of four flaunted her famous figure in the snap as she wished her close friend a happy birthday.

Kim has continued her trend of showing off her body in photoshoots and online, but now with her more slimmed-down frame.

Earlier this week, the socialite nearly busted out of a tiny pink bikini in a new social media post.

The brunette reposted an ad for her latest collaboration with the wellness brand, Alani Nutrition.

In her post shared on her Instagram Story, Kim had on a full face of makeup.

The Skims founder flaunted her toned oiled-up body wearing a teeny pink stringed bikini while holding onto a pink can titled Kimade.

Kim stood in front of a pink background with water droplets falling down the wall.

The Hulu star also held onto a pink towel while sporting a matching colored headband and goggles.

"Keep your Kool," was printed next to Kim.

Earlier last month, Kim stunned in a white bathing suit while promoting her new drink.

She shared pics on social media from a photoshoot of her sporting a body-hugging white one-piece, showing off her skinny arms and legs.

She paired the look with high heels, flashy diamond jewelry, a full face of makeup, and a platinum blond wig.

Each snap showed Kim in various poses - several of her nearly popping out of her ensemble while sitting on an exercise bench and holding small weights.

But recently, Kim sparked concern after showing off her tiny waist in another series of photos.

The star displayed her thinner-than-ever frame in a cropped white T-shirt and low-slung jeans while attending a soccer match in Miami.

Kim accentuated her shrinking frame with a thin pink belt tied around her hips and completed the outfit with a Hermes bag.

The reality star - who lost 21 pounds last summer - posted the snaps from last week, when she attended the Inter Miami game with her son Saint.

She captioned the post: "Legendary Inter Miami game!!!!"

Fans shared their fears over Kim's figure in the comments, with one writing: "Woah she looks really skinny."

Another agreed, adding: "Yeah it's a bit much even for Kim."
