People Editorial Guidelines Published on February 7, 2019 12:23 AM Share Tweet Pin Email Kim Kardashian West and her sister Kourtney Kardashian are back in black! On Wednesday night, the reality stars stepped out in New York to attend the 2019 amfAR Gala together. For the second time in three months, the sisters opted to coordinate looks — but this time around, they got far more revealing. At the glamorous event, which was held at Cipriani Wall Street and serves as the unofficial kickoff to New York Fashion Week, Kim, 38, wore a plunging black Versace gown that showcased her cleavage and had thigh-high slits on its side. The Keeping Up with the Kardashians star kept the rest of the look low-key, wearing clear-strapped heels and her hair down in waves, while her makeup featured her usual smokey eye and natural lip color. Theo Wargo/Getty Kourtney also went for a simple yet dramatic look. Though she matched her younger sister in a Versace black gown, Kourtney’s style featured a scoop neckline that came to a point in the center and pushed up her cleavage. The dress also included thick shoulder straps and a thigh-high slit, which allowed the reality star to flaunt her toned leg with black pointed heels. To complete the look, Kourtney, 39, wore her hair in a slicked-back, high ponytail and added a smokey eye and natural lip color. Kim later tweeted about the evening and thanked the acclaimed design house for allowing her to wear its gowns. “So happy to honor Mert and Marcus tonight!!!!,” she wrote referring to photographers Mert Alas and Marcus Piggott, before adding, “Thank you Donatella & @Versace for lending me this stunning vintage gown for tonight” The last time the sisters coordinated their formal attire was back in November when they stepped out for the 2018 LACMA Art + Film Gala in Los Angeles. Their look on Wednesday very closely resembled the ones they wore three months ago.

Like Wednesday evening, she kept her hair down and opted for the smokey eye look. Kourtney, however, kept things more subdued in her floor-length halter gown with an open back. Similar to the New York gala, the reality star passed on jewelry and pulled her hair back into a slightly-lower ponytail. She also carried a small black bag. But it is not just black formalwear that the sisters have coordinated looks on. They also previously went matchy-matchy in casual attire for a brief pit stop at a convenience store, each sporting an oversized gray sweatshirt, matching sweatpants and white sneakers.

The star was spotted getting lunch in L.A. with Kourtney and her ex Scott Disick on Monday, sporting an all-black outfit including a turtleneck top, black jacket and dark sunglasses. She also appeared to have some sort of breakout. DailyMail.com called out the imperfections in an online post and tweet, which read that Kim suffered from a “bad skin day.” And on Tuesday, Kim responded to their Tweet.

The last time that Kim revealed that she had a flare-up was at the end of December 2018. She tweeted, “I think the time has come I start a medication for psoriasis. I’ve never seen it like this before and I can’t even cover it at this point. It’s taken over my body.” The star first found out she had the condition when she was diagnosed by a dermatologist on an episode of Keeping Up with the Kardashians in 2011.
