Bathing Suit Trends for 2026: String Cuts, High-Leg Bikinis and Tan-Friendly Styles

The swimwear landscape heading into 2026 draws from a mix of retro references and modern performance thinking. Styles once associated with the 1980s and early 90s are back in a more refined form, blending nostalgia with technical fabric upgrades and body-inclusive design. For Australian swimmers, surfers, and sunbathers, staying across these shifts means finding pieces that actually suit how and where you swim.

Bikini Cuts and Fit Tips

The cut of a bikini has a significant effect on both comfort and appearance. High-leg cuts continue to dominate in 2026, elongating the silhouette and reducing fabric bulk around the hips. Brazilian cuts offer minimal rear coverage and remain popular for sunbathing. Meanwhile, cheeky cuts sit somewhere in between, offering a balance of coverage and style. When choosing a cut, consider your activity level. Fuller coverage tends to stay in place better during active water sports, while minimal cuts are better suited to lounging poolside. Always check that the bottom sits flat against the body without gaping or digging in at the leg openings.

String Swimwear Comfort and Support

String bikinis are having a strong moment, particularly styles with adjustable ties that allow for a more personalised fit. The appeal lies in their simplicity and the ability to customise coverage. However, string swimwear is not always the most supportive option for larger busts. Thicker string styles and those with built-in shelf lining or underwire provide more structure without sacrificing the aesthetic. Look for wide-set ties and reinforced knot points if you plan to swim laps or spend extended time in the water. Comfort comes down to the combination of stretch, fabric weight, and how the strings are positioned across the body.

How to Choose Flattering Swimwear Shapes

Flattering swimwear is less about hiding and more about proportion. One-pieces with ruching across the midsection create visual softness, while cut-out details draw the eye strategically. High-waisted bikini bottoms paired with a crop-style top create a balanced look that many find both stylish and comfortable. For those with a longer torso, two-piece styles allow for separate sizing on top and bottom, which makes a noticeable difference in fit. V-necklines and plunge cuts tend to work well across a range of body shapes by drawing the eye upward. The key is to try different proportions and not default to the same style each season.

Sunbathing-Friendly Swimwear Materials

Fabric choice matters significantly when it comes to tanning and sun exposure. Lighter-coloured or open-weave fabrics can allow more UV light through, which affects both tanning and sun protection. Most quality swimwear uses a nylon and elastane blend, which resists fading, stretching, and chlorine degradation. Some brands now offer swimwear with a built-in UPF rating, which is particularly relevant in the Australian context given the intensity of UV exposure. For sunbathing specifically, thinner fabrics with minimal padding reduce tan lines while maintaining shape. Matte finishes are generally better at retaining colour over time compared to shiny or metallic fabrics.

Care and Wear for Pool and Beach

Swimwear longevity depends heavily on how it is cared for after each use. Chlorine and saltwater both degrade elastane fibres over time, leading to sagging and colour loss. Rinsing your swimwear in cold fresh water immediately after swimming is one of the most effective ways to extend its life. Hand washing with a mild detergent is preferable to machine washing, and swimwear should always be dried flat in the shade rather than in direct sunlight or in a dryer. Avoid sitting on rough surfaces like concrete or timber decking in your swimwear, as this causes pilling and wear on the fabric base. Rotating between two or more pieces also allows each one to recover its shape between wears.

Swimwear choices in 2026 reflect a broader shift toward styles that combine visual appeal with practical performance. Whether you are drawn to the minimal lines of string bikinis, the structured support of underwired tops, or the full-coverage elegance of a contemporary one-piece, the range available to Australian swimmers is wider and more considered than ever. Understanding the relationship between cut, fabric, and care means getting more wear out of each piece while looking and feeling comfortable in it.
