Cara Delevingne & Kate Moss #SelfieSwap After The Mango Flagship Party — PHOTOS

Right after hosting a jam-packed party at Mango's new flagship store in Milan, British besties Kate Moss and Cara Delevingne did what any pair of jet-setting fashion icons would do; they headed back to the hotel for some R&R — but not before immortalizing an impromptu photoshoot in their underwear, first. Delevingne then shared the photographs, which she captioned "Super Kate" and "Super Women", on her Instagram account, tagging photographer pal Mert Alas as well, who also shared the images on his own account.

The pictures were both curiously tagged #SelfieSwap, although neither is, by definition, a selfie; Delevingne took the photo of Moss, who appears in sheer tights, skimpy skivvies, and a black bra sprawled across a plush-looking hotel bed, and Moss snapped Delevingne atop the sheets in a fur coat, no bra, and Superwoman undies, with tattoos in full display.

Perhaps it has something to do with Alas' reputation as the "King Of Selfies" a title bestowed on the photog by Irina Shayk. Alas, who regularly shoots editorials and covers for Vogue, Interview, and more, is responsible for the September issue of Interview Magazine, which feature screen-shot images of Kim Kardashian, Miley Cyrus, and Alas himself.

Moss' photo, above, seems relatively tame compared to Delevingne's, which she had to censor with a strategically-placed star as per Instagram rules. (#Freethenipple!)

Both were still rocking full hair and makeup looks from the Mango party earlier that day, and Moss still has on an elegant pair of chandelier earrings.

Hey, I'm with them on that count — the hardest part of getting ready for bed is taking off your makeup and jewelry, especially when it looks so perfect; sometimes you just have to get a few more photos in before lights out!

These ladies are just always #twinning aren't they? Check them out at the Burberry show during London Fashion Week.
