Light your cig, sip your gimlet and cloak every hair on your head with a thick layer of hairspray — we're traveling back in time to the swinging '60s, sweeties! 

Last evening, Chrissy Teigen threw a '60s-themed birthday bash at LAX's vintage (and not in use) Pan Am hangar that was attended by the likes of friends Jen Atkin, Kris Jenner and, but of course, Kimye!

It seems the couple might be back to their old power couple ways — at least judging by their function 'fits. Kim came correct — after all, she recently had practice channeling the era when she and Northie posed for Interview Magazine as the modern day Jackie Bouvier Kennedy Onassis and Caroline Kennedy. Wearing a light pink vintage Chanel suitdress, Jackie O.-style sunnies and a beehive-style hairdo, Kim K. looked every part like the picture perfect Mad Men extra. Kanye skewed toward a dark color scheme, opting for a full-length suit jacket. 

Kanye willingly smiled for a picture, perhaps a telling sign that Chrissy's party was a smashing success! Get a look inside the themed soiree below.
