"What Our Gearhead® Experts Are Saying: ""I like these bottoms for days when I want a playful fit that still feels comfortable in the water. The tie sides make it easy to dial in the fit, and the stretch fabric stays put while swimming. They’re a great option for mixing and matching with different tops."" When our swim days are all about sun, saltwater, and easygoing style, we reach for the Last Summer Tropic Tie Side Bikini Bottom from Billabong. Designed to feel light and fun, this bottom brings a confident, beach-ready look that’s perfect for long afternoons by the water. The low-rise silhouette and cheeky coverage create a flattering, surf-inspired fit, while adjustable tie sides let us fine-tune comfort on the fly. Soft, stretchy fabric moves easily whether we’re swimming or relaxing on the sand, and contrast binding adds a clean finish. Finished with subtle embroidery at the back, this bikini bottom is made for mixing, matching, and soaking up summer."
