Nothing comes between Gigi Hadid and her Calvins.

Pre-pregnancy, the 25-year-old supermodel stripped down to her skivvies to star in the campaign for Calvin Klein’s new underwear collaboration with Kith.

Inspired by the American fashion brand’s iconic ’90s aesthetic and photographed by Cass Bird, the ads see Hadid going topless in a pair of distressed denim, with the collection’s undies — the waistbands for which combine both Calvin Klein’s and Kith’s logos — peeking out over the waistband.

As the model excitedly shared on Instagram last week, one of the sexy shots is currently occupying an enormous billboard in NYC’s Soho shopping district.

In another shot, the blond beauty lounges on a bed wearing a pair of boxer briefs and an unbuttoned men’s shirt.

For those seeking something less sporty and more sparkly, there’s also a shimmering gunmetal-colored bra and panty set with both “Calvin Klein” and “Kith” spelled out in sparkling stones, which Hadid modeled with an edgy black leather jacket.

Priced from $30 to $70, the Kith for Calvin Klein collection launches on Saturday, Sept. 12, at Kith shops and at 11 a.m. ET on Kith.com — so better start practicing your sultry poses now.
