Heidi Klum Wears Hip-Cutout Pants and a Bikini Top For Anniversary Date Night

Heidi Klum is really taking advantage of the last half of summer. She's traveling through Europe on a trip with her husband, Tom Kaulitz — and showing off all of her new colorful bikinis while she's at it. The latest? A printed string bikini and matching pants, worn while celebrating the couple's fourth wedding anniversary.

The bikini consisted of a classic string top, paired with matching printed pants that boasted naval and hip cutouts with strings that crisscrossed on both sides. Around her neck were layered charm necklaces and pendants.

Klum shared a number of outfits as part of an Instagram slideshow on Thursday, including a colorful crochet bikini and a floral lace minidress. She documented her time dining al fresco, riding on a moped through the streets, and walking around the costal town with the caption: "Ich bin soooo verliebt in Dich Tom Kaulitz ❤️❤️❤️❤️ Happy Anniversary mein Liebling 🥰," which translates to "I'm sooooo in love with you Tom Kaulitz. Happy Anniversary my darling."

Klum has been sharing several bikini snaps from her midsummer trip, which means endless swimwear inspiration. She rocked a crochet pink and white bikini and classic black two-piece, to name a few. She even integrated swimwear on the red carpet, wearing a half bikini, half black-tie gown at the Jean Paul Gaultier show during Paris Couture Week.
