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

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

The law student added a pair of loose-fitting blue track pants with red and white stripes going 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 pair of gray Yeezy slides.

Her raven-hued locks flowed freely, stretching down to her backside in a center part and uniform waves.

Kim removed her sporty black sunglasses as she headed into the building where he son was set to play.

She wore a black watch on her left wrist and sported one of her favorite jewelry pieces – a diamond-encrusted nameplate that reads KIM.

The underwear and swimsuit designer carried some belongings in a fuzzy black handbag.

Her famous visage was covered in expertly-applied makeup that accentuated her features.

Kardashian, who made a name for herself on Keeping Up With The Kardashians, was by herself as she arrived.

Her pants had a scrunched elastic band that highlighted her famously trim waistline.

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

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

‘Alright I’m going to try on some of our SKIMS Swim,’ she announced in her signature soft and bubbly voice.

‘I really love this pink bandeau, it is so cute. I love 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 I love,’ she said. ‘I love the triangle top with the sequins, so cute.’

The marketing maven noted, ‘I love a good coverup so, I love these pants, ’cause they’re really cute just to cover up and wear over if you’re going to lunch by the beach or anything like that.’

‘I always love something that you can cover up with too,’ she added.

It comes after earlier this week Kim paid a visit to Los Angeles County’s California State Prison in Lancaster 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.

Following the visit, she said: ‘It’s always an honor to be able to visit the men and women living behind our prison walls’
