What makes Sea Level swimwear unique?
Sea Level combines elegant swimwear design with body-sculpting support. They use powermesh lining for subtle shaping, soft cup support, and adjustable elements to create a personalised fit. Their minimalist designs and modern silhouettes make them stand out from more traditional swimwear brands. It’s flattering without feeling overdone.
Is Sea Level swimwear eco-friendly?
Yes—many Sea Level styles are made from recycled nylon fabrics, offering both sustainability and performance. These fabrics are soft, durable and hold their shape beautifully, even with frequent wear. It's swimwear you can feel good about wearing, in more ways than one.
Does it offer bust support?
Absolutely. Most Sea Level swimsuits include built-in soft cups, shelf bras or hidden underwire for light to moderate support. Adjustable straps and structured panels provide lift and shape. While not D+ specific, the designs cater well to a range of sizes and provide great everyday comfort and security at the bust.
What sizes does Sea Level offer?
Sea Level typically ranges from AU size 8 to 20. The fit is true to size with a structured feel thanks to the inner mesh and supportive construction. Many of the styles are designed to flatter and shape the waist and bust while offering good rear coverage as well. We’re happy to help with sizing advice in-store or online!
How should I care for this swimwear?
Rinse after each wear and hand wash in cold water with a gentle detergent. Avoid rough surfaces and excessive sun exposure to preserve elasticity and colour. Lay flat to dry and avoid tumble drying. With the right care, your Sea Level pieces will stay supportive and stylish swim after swim.
