Sea Level is an Australian swimwear brand built around a single, genuinely unusual commitment: fit first. Where most swimwear brands start with aesthetics and work backwards, Sea Level starts with how the garment should feel and function on a real body — then designs around that.

Their Multifit technology is the clearest expression of this philosophy. Instead of one size per garment, Multifit offers the ability to size the top and bottom of a one piece independently — solving the single most common fit problem in women's swimwear. If you are a size 12 on top and a 16 on the bottom, Sea Level has a solution that most brands do not.

Sea Level's range covers one pieces, bikini tops, tankini tops, swim dresses and chlorine resistant styles. Their D-G cup range is one of the most comprehensive available in Australia, with full cup sizing built into the structure of the garment rather than added as an afterthought. They also produce mastectomy styles with integrated prosthesis pockets.
