More than 50 athletes, including Serena Williams, Sha'Carri Richardson, and Jordan Chiles, are featured in NikeSKIMS' debut campaign.

There are 58 silhouettes and seven collections in the brand.

On Monday, Sept. 22, the billionaire launched the first collection from NikeSKIMS, a new brand created in conjunction with Nike.

 According to a press release, there are almost 10,000 ways to mix and match the pieces in the line's seven collections and 58 silhouettes.

"It feels like butter on your skin," Williams, 43, said of the collection via the press release. "I feel unstoppable when I’m training in it."

Richardson revealed, "I feel free and confident when I'm wearing NikeSKIMS. Knowing that I can look and feel this amazing while working hard makes me feel powerful.

Kardashian stated in an interview with Vogue that a collaboration between SKIMS and Nike "just made sense."

"Skims is very body-oriented — we do swimwear, loungewear, shapewear — so our next evolution was that we really wanted to do activewear," she said.

"Our dream was to work with Nike: Their legacy, innovation, and athlete insights — it was the perfect thing to mix with Skims, and our dedication to the female form."
