Heidi Klum transformed an itty bitty beachwear staple into a cool girl city statement piece as she stepped out on Monday, June 16. The former America’s Got Talent judge has been in peak bikini mode while promoting her new Calzedonia campaign, and Klum found a way to integrate the tiniest string bikini into a Canadian tuxedo as she made an appearance across the pond.

The supermodel kicked off the week in Cologne as she unveiled her new Calzedonia billboard in the German city. Despite the urban setting, Klum managed to infuse some vacation vibes into the event by pairing a denim-on-denim look with a pool-ready bikini top. The star turned heads as she bared her torso in a sky blue string bikini top with ruching on its bra cups. Klum leaned into a monochromatic palette with a similarly-hued jean jacket, which she wore open to expose her swimwear underneath. Styling her jacket off her shoulders to show off her suit, Klum—who wore a matching pair of high-waisted straight leg jeans with strappy blue sandal heels—posed for photos as she spray painted her signature on the billboard photos.

The star styled her long blonde hair in beachy middle-parted waves and added some subtle shine in gold half-moon hoop earrings and a pair of gold-rimmed aviator glasses with brown lenses. She subtly accentuated her features with peachy nude lips, bronzed skin, and brown smoky eyes.

Klum’s swimwear-meets-street-style moment comes shortly after she donned a Calzedonia swimsuit for a gardening day last week. Dancing to Tate McRae’s “Sports Car,” the former Victoria’s Secret Angel could be seen wearing a skimpy nude string bikini embellished with gold ring accents as she seductively watered plants in her garden. Klum went for a sultry bedhead look for the video, pairing her tousled blonde waves with her signature smoky eyeshadow.
