Kris Jenner made an appearance at the Amazon Prime Summer Soiree at Los Angeles' Sunset Tower on July 16 and stole the spotlight away from her supermodel daughter, the Daily Mail reported. Momma Jenner, 59, outshined 19-year-old Kendall in a sexy sheer top.

Kris wore an all-black pantsuit, one of her signature looks, with a high-waisted, ankle-grazing, slim-leg trouser and an oversized blazer. But she kicked the risque factor up a notch by layering a sheer black top with a shimmering pearl embellishment design over nothing but a well-fitting bra, showing off the perfect amount of sexy cleavage. She paired the outfit with a simple yet chic pair of strappy black heels, her short hair styled in an effortless tousled look, and added a bit more edge with a nude lip and a black smoky eye.

Her daughter Kendall showed up wearing an oversized oatmeal-colored cardigan over a knee-length dress. Kendall made her legs the focal point of her outfit and showcased them even more with light camel-colored stiletto booties. Her outfit choice might have been the result of her mom's habit of planning last-minute outings with her daughters.

"I love being with my kids," Kris told Us Weekly. "I was on my way here to support the girls, the Foster girls, and I called Kendall and said, 'Get over here, let's go there for a minute and I'll take you to dinner.' That's the way it goes in my family, it's always spontaneous."
