Kim Kardashian puts on a busty show in a tiny bra and pajama bottoms as she brushes off fans' reactions to Balenciaga deal

Kim Kardashian once again proved to be her own best advertisement for her shapewear brand when she modeled her upcoming Valentine's Day collection.

The SKIMS founder, 43, showed off her stunning physique in a number of looks released ahead of the annual holiday on February 14.

Kim's latest post came shortly after she received a wave of backlash from fans about signing with controversial brand Balenciaga as their new ambassador.

The deal with Balenciaga comes just a year after the brand faced controversy over an ad featuring children and BDSM items.

In the clip, Kim's perky assets were on full display in a tiny pale pink thong bra, which was tied at the bust and covered in pretty velvet hearts.

The barely-there garment, which showed off her toned midriff, was paired with matching pajama bottoms in the same fabric.

Kim, who was standing in her dressing room, turned to show what the loungewear ensemble looked like from the back.

Kim told her followers that the new line would drop the next day [January 23]as she prepared her fans to jump on her latest collection.

Despite the comfortable attire, Kim still made sure she looked glamorous as she opted for a full face of flawless makeup and wore her raven locks in a loose, glossy style.

As she filmed herself in the mirror on her phone, Kim could be heard saying, “How cute is this!”

Kim modeled a second outfit and later donned a silky pale pink two-piece suit, with hot pink lace detailing.

Meanwhile, her sister Kourtney, 44, also showed off her bedtime clothes as she filmed a new ASMR video for social media.

Kourtney was tucked up in bed wearing silk pajamas as she shared her bedtime routine with her followers on Instagram.

Kourtney lit a candle as she relaxed in bed with her book, before taking a sleep gummy and putting on her eye mask.

Kim announced her collaboration with the label on Monday, led by creative director Demna Gvasalia.

She refused to cut ties with the fashion house but said she was “shocked and disgusted” by the images that sparked a backlash against the brand.

Following the announcement of her new collaboration, many fans were disappointed by the decision and pushed back on her statement, writing that her relationship with the brand was built on a “commitment to doing what's right.”

'Of all the brands, she had to choose the brand with accusations of child abuse. But not even surprised…' one wrote, while another branded her a 'hypocrite' and added: 'Money is all that matters to her.'

Another person accused Kim of throwing her “morals out the window” for money, while someone else added: “Anything for money and a higher net worth, I guess.”

“Where will she keep all the money and fame when she's gone?”

“So we forgot about the child bondage thing? lol,” one commenter asked.

“But Kim, this company does everything but what is right,” another added in reference to her statement.

The comments continued to pour in, with another asking: “So Kim just forgot what Balenciaga was advertising with the kids?” K.'

“Hasn't she learned anything?” someone else asked.

“Even after the scandal?” asked another Twitter user.

One comment simply read: 'Girl… Embarrassing.'

Others called out the SKIMS founder for hypocritical behavior: “So basically she said f**k Balenciaga when they were criticized, but now that it's safe for her brand she's back?”

Many others turned against the brand, calling it “garbage” and “cancelled.”

Kim's full statement on how she became an ambassador for the brand read: “Balenciaga designs have been part of my many looks for a number of years – and some of my most iconic fashion moments.”

'This historic fashion house embraces modernity, craftsmanship and takes an innovative approach to design under Demna.'

'For me, this long-term relationship is based on mutual trust and the commitment to do what is right. I'm excited about this next chapter for the brand and becoming their ambassador.”
