Sea Level Australia designs modern swimwear that fits, supports and flatters—without ever compromising on style. This Australian brand is known for its clean lines, elevated cuts and technical details like powermesh lining, adjustable straps, and bust support. Whether you’re looking for a sleek one-piece or a versatile bikini set, Sea Level offers refined swimwear for every body.

At The Foundation, we love Sea Level’s clever use of recycled fabrications, soft textures and minimalist styling. Their silhouettes are body-conscious but never restrictive, featuring subtle shaping and timeless appeal. From sculpting surfsuits to versatile separates, this brand is ideal for women seeking a balance of comfort, coverage and confidence.

If you're looking for swimwear with understated elegance, functional design and inclusive sizing—Sea Level ticks all the boxes. It’s swimwear you’ll feel good in, season after season.

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.
