Kim Kardashian rocks a busty white tank top for son Saint’s basketball game in LA

Kim Kardashian stepped out in style on Friday when she attended her son Saint’s basketball game in Thousand Oaks, California.

The 42-year-old SKIMS mogul — who posed in new pieces from the brand earlier today — wore a tight white tank top that showed off her slim torso.

The law student added baggy blue sweatpants with red and white stripes down the sides.

The stylish mother of four, who shares North, 9, Saint, 7, Chicago, 5, and Psalm, 3, with ex Kanye West, added a few gray Yeezy slides.

Her raven-colored locks flowed freely and extended to her back in a center parting and uniform waves.

Kim took off her sporty black sunglasses as she entered the building where his son was to play.

She wore a black watch on her left wrist and wore one of her favorite pieces of jewelry: a diamond-encrusted name tag that read KIM.

The underwear and swimwear designer was carrying some gear in a fuzzy black handbag.

Her famous face was covered in skillfully applied makeup that accentuated her features.

Kardashian, who made her name with Keeping Up With The Kardashians, was alone when she arrived.

Her pants had a crinkled elastic band that emphasized her famous waist.

Earlier in the day, the entrepreneur shared new products from her SKIMS line in a series of Instagram Stories.

One was a cotton candy pink bandeau style bikini top that she modeled for her more than 350 million followers.

“Okay, I’m going to try on some of our SKIMS Swim,” she announced in her trademark soft and sparkling voice.

‘I really like this pink bandeau, it’s so cute. I like the little bandeau,” she added.

In another clip, she wore a light blue triangle top with blue sequins along the edges of the cups.

“This really cute top that I love,” she said. “I love the sequin triangle top, so cute.”

The marketing expert commented, “I like a good coverage, so I love these pants, because they’re really cute to cover up and wear when you go to lunch at the beach or something like that.”

“I always like something you can hide too,” she added.

It comes after Kim visited Los Angeles County California State Prison in Lancaster earlier this week with her younger sister Khloe, 38.

Their visit was part of REFORM Alliance’s Future Shapers Advisory Council, and Kim explained that she wants to use her platform to “change the lives” of those behind bars.

After the visit she said: ‘It is always an honor to visit the men and women who live behind our prison walls’
