Kourtney Kardashian Highlights Her Décolletage in Saint Laurent Tux

The theme of the evening was eye candy, and that’s exactly what Kourtney Kardashian served.

The 37-year-old sizzled in Saint Laurent when she arrived for alice + olivia’s new eyewear launch on Wednesday in Los Angeles.

With no bra, the Keeping Up With the Kardashians reality star highlighted her décolletage in Saint Laurent’s black tuxedo blazer teamed with matching trousers and pointed-toe patent leather pumps.

The label’s iconic “Le Smoking” jacket features satin lapels and is fully lined in silk. It’s available for $3,505 on Net-a-porter.com.

It would be no surprise if she completed the sleek look with another classic by Saint Laurent, the luxury brand’s “Paris Skinny” pumps. The footwear incorporates a curvy topline on a 4-inch slender stiletto heel, and it retails for $595 on Nordstrom.com.

Kardashian joined alice + olivia’s CEO and creative director Stacey Bendet at the event while celebrating the launch of Bendet’s new collection of sunglasses, featuring 16 styles ranging from $250 to $525.

Bendet presented the eyewear along with complementary shoes from her line, including the “Madison Floral” sunnies ($525), featuring Swarovski-crystal embellished petals, with “Carla” floral heels ($425).

The label’s “Pemton” sneakers ($195) had an apt companion with the same wildflower Chelsea pattern in the “Melrose” and “Dinah” eyewear frames.

Guests included Olivia Culpo, Leona Lewis, Lydia Hearst-Shaw, Michelle Trachtenberg and Freida Pinto.
