What they've been missing! Kourtney Kardashian goes for the side plunge in provocative black gown at Harper's Bazaar bash

She skipped Kanye West's fashion debut on Wednesday to her brother-in-law's chagrin.

Kourtney Kardashian made up for lost time in a very revealing way as she attended Harper's Bazaar's ICONS Portfolio by Carine Roitfeld at the Plaza Hotel in New York City on Friday.

The 37-year-old mother-of-three showcased her svelte yet shapely figure in a black one-strap gown with high-low skirt and two splits.

Steal Kourtney's red carpet style in an asymmetric dress by Anthony Vaccarello

New York Fashion week has been all about Kim Kardashian and Kendall and Kylie Jenner so far but now they've been joined by Kris Jenner and Kourtney Kardashian, making it a real family affair.

And Kim and Co should watch out because with Kourtney looking so fly she may just steal the limelight. The mother of three looked fantastic as she posed up a storm on the red carpet at the Harper's Bazaar party last night.

This asymmetric dress is gorgeous on her and we love the flowing draped hem which works to show acres of leg, while the one shoulder cut is super sexy. It's by Anthony Vaccarello and the good news is it's available to buy now.

Kourtney wasn't shy about showing so much skin - her sister Kim does it all the time - and followed the family tradition by exposing much of her legs.

She matched her slinky ensemble with a pair of ankle-strapped high heels that made her legs seem even longer.

Her long dark hair was gathered back in a luxurious style that displayed the wide hoop earrings.

Like her sister Kim, Kourtney preferred a neutral-toned look where her make-up was concerned, opting for nude lip gloss and beige and brown eye shadows, and shimmering bronzer.

Kourtney, meanwhile, missed the kick off of New York Fashion Week - including brother-in-law's Yeezy show - due to a European vacation on a luxury yacht.

But earlier on Friday, Kourtney was spotted stateside as she stepped out in a denim jumpsuit in the Big Apple.

The brunette beauty hit the busy streets rocking a slim-fit blue jean romper which showcased her petite physique.

Kourtney, who was recently spotted showing off her toned swimsuit body in the South of France, was more covered up for her outing in New York. 

The mother-of-three still managed to show off her svelte figure in a chic curve-hugging denim jumpsuit.

The stylish short-sleeved onesie featured a front zipper and pockets along with the on-trend wide-legged silhouette. 

She added white platforms to her effortlessly cool look and accessorized with a black leather tote bag.

The brunette beauty wore her long straight locks down to cascade past her shoulders and shielded herself from the sun with a pair of over-sized black shades.

At one point during her outing she was seen carrying her youngest son, Reign, 18-months, on her hip.

The little cutie also wore a onesie put his was white with black speckles and went sans shoes.

The hot mama, who's been on holiday in France, was joined by her children Mason, six, Penelope, four, and Reign as well as momager Kris Jenner and her beau Corey Gamble during the European getaway. 

All of whom were noticeably absent from Kayne West's Yeezy show, which garnered mixed reviews, on Wednesday at New York Fashion Week.  

'It was a big disappointment to Kanye that Kris, Kourtney and Khloé didn't attend his fashion show,' an insider told People on Thursday.
