Mediterranean-inspired Sienna & Sierra branded recycled string bikini
If my summer suitcase could talk, it would demand this bikini. Inspired by vintage Mediterranean tiles and seaside wanderlust, the print bursts with swirls of cobalt blue, golden sun tones, and turquoise sea vibes. Perfect for lazy beach afternoons, poolside lounging, or that spontaneous yacht invite (yes, ferries count too).
Made with a soft, stretchy blend of recycled polyester (81–88%) and elastane, this bikini is UPF 50+ and fully certified (OEKO-TEX 100 + GRS) — stylish and planet-friendly. The top comes with removable padding for comfort, and the ties let you switch up your style whenever the mood hits.
Every design in our Sienna & Sierra swimwear line is dreamed up by us — unique, wanderlust-fuelled pieces that proudly carry our brand’s signature touch. If you love this look, check out our retro circle sun tile one-piece and Pink Checkerboard Bikini for more seaside adventure energy.
Best Colours: Pair with white linen, raffia accessories, or gold jewellery for effortless coastal chic.
Avoid Colours: Anything too neon — let the Mediterranean palette do the talking.
