Miranda Kerr, Chiara Ferragni, Leandra Medine Post Semi-Nude Selfies for Calvin Klein Campaign

Remember those moody Calvin Klein underwear ads that were scattered across all your favorite magazines in the '90s? Well, they're back, but this time, they're popping up all over your social media newsfeeds. Calvin Klein recently launched a social media-driven campaign, enlisting celebrities and style influencers to show off their CK undies on their Instagram accounts. After sending product to each CK ambassador, they then styled their undies in their own unique way and posted the photo with the following tag: #MyCalvins.

"We thought it would be groundbreaking to actually start a campaign with influencers posting images before we even posted images," said Malcolm Carfrae, Calvin Klein executive vice president and chief of communications. We have to say, we think it's working. Take a look and see for yourself.

And in the event you're interested in taking your own CK undie selfie, you can buy yours here and here.
