Kendall Jenner shows us how to pair a belly chain with a tweed skirt suit

Do you hear that, friends? It’s the sound of 1,000 “rules” for workplace attire self-imploding. And it’s all thanks to Kendall Jenner, who wore a tweed skirt suit with a belly chain last night and looked like a GD boss.

Stopping by The Tonight Show Starring Jimmy Fallon on Valentine’s Day, Jenner gave a sartorial shout-out to the occasion of ~love~ in a pink Chanel suit, adding her own signature sexy streak with a crop top and exposed body jewelry.

We can’t imagine Jackie O rocking her iconic pink Chanel suit in quite this fashion, but hey, Kendall is a new icon for a new generation — and her look werks.

(By the way, you’d be excused if you thought this was Kylie Jenner and not her big sis Kendall. With that bob and overdrawn pout, we had to do a double take when we saw this photo!)

Now about that suit: In addition to a full neck-to-middrift body chain, Jenner wore a gold necklace with oversized round charms and layered that with a gold chain choker. Very rap-video-meets-MadMen, if you ask us.

As she departed the show, Jenner swapped her pink heels for sneakers and topped off her sexy business look with a white fur coat to keep out the chilly New York night air.

Still so damn chic.

Kendall’s been making the rounds at New York Fashion Week recently, modeling for designers including La Perla and Michael Kors. Her career has been on a rocket ship these last few years, and we can only imagine what the future holds. Keep shining, lady!
