Kourtney Kardashian turned 36 on Saturday, and lots of heartfelt greetings poured in from her loved ones, including her sisters, on Instagram. But, of course, her birthday celebration would not be complete without a grandiose party!

The mother-of-three flew into Las Vegas on her birthday for a night of fun at 1 OAK Nightclub. She looked amazing as she displayed her curves and shapely pins in a black long-sleeved top and accentuated her waist in a pleated skirt with a jersey panel.

Her accessories were very simple — only a few rings and a pair of earrings. Kourtney let her long raven locks fall loosely over her shoulders and kept her makeup gorgeous with lashings of mascara, glittery eye shadow, and pink lip gloss.

We love that the eldest of the Kardashian sisters kept things simple in this all-black number. She followed the fashion rule, showing only her legs and keeping the rest of her skin covered.

Kourtney’s fun and flirty outfit was styled with lace-up sandals from one of her favorite brands, Tom Ford. They feature lace-up fastenings, tapered gold toes, gold-tone studs, 0.5-inch platforms, and 4.5-inch heels.

The following morning, Kourtney shared this photo of herself pumping breast milk. Not surprisingly, the seductive image caused quite a stir online.

Coincidentally, a recent study reported by CNN showed that breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings.
