Is it better to size up or down in swimsuits?

If you’re unsure about your size, our Fit Guide helps you find the perfect fit so you can enjoy your swimwear with confidence and comfort — every time you wear it.

High-quality materials, fairly made in Europe

Each MYMARINI swimsuit, bikini, or ready-to-wear piece is carefully crafted in Europe using durable, high-performance fabrics like ECONYL® — a regenerated nylon made predominantly from pre- and post-consumer waste such as industrial plastic, fabric scraps, and even rescued fishing nets that would otherwise pollute our oceans. This premium material ensures our products’ softness, resilience, and top performance in any setting — whether you’re swimming laps in the pool, diving into the waves and enjoying the sun at your favorite beach, or even doing yoga or playing with your kids at your local playground. Chlorine resistance helps maintain the shape of our swimwear over time, and UPF 50+ protection is woven into the fabric to ensure consistent sun protection.

Our commitment to sustainable production means we do our best to make every step of our process — from sourcing to finishing — as transparent and fair as possible.
