Swimwear trends: string bikinis, high-cut legs and tan-through swimsuits

Swimwear trends often get summarized by a silhouette, but what matters day to day is how a suit feels during real activities: walking on hot sand, swimming, paddleboarding, or sitting on a dock for an afternoon. This season’s popular looks include lighter, more adjustable string constructions, higher-cut leg lines, and experimental textiles sometimes described as tan-through. When you look beyond the visuals, these trends are also about engineering—strap placement, seam design, lining choices, and fabric performance.

High-cut bikinis and string styles

High-cut bikinis and string styles are showing up across many collections because they are relatively adaptable to different preferences. A higher-cut leg opening changes where the side seam sits on the hip, which can affect mobility and how the suit stays in place when you move. String styles usually rely on ties at the neck, back, or hips, making it easier to adjust tension rather than relying on a single fixed band.

For general-audience practicality, two construction details matter more than the overall shape. First, look at strap width and hardware: slightly wider straps or reinforced tie channels tend to hold their shape better during swimming. Second, check the lining and seam finish: smooth, well-finished edges reduce rubbing, especially after repeated exposure to salt water or chlorinated pools. If you plan to be active, consider designs marketed for sport or multi-activity use, which often add stabilizing features like stronger elastic, more secure back closures, or extra support in the top.

Tan-through swimsuits and modern materials

Tan-through swimsuits are typically made using more open-knit or micro-perforated fabric structures designed to allow more light to pass through compared with traditional, tightly knit swim textiles. In practice, performance can vary significantly. The amount of light transmission depends on fabric density, colour, stretch, whether the suit is lined, and how close the fabric sits to the skin. Many suits also add lining in key areas for coverage and comfort, which can reduce any tan-through effect.

It’s also helpful to separate “tan-through” marketing from broader material innovation. Modern materials may prioritize faster drying, improved stretch recovery, and better resistance to chlorine and abrasion. You might see labels such as chlorine-resistant, shape-retaining, or UV-related features, but these are not universal standards and results differ by brand, fabric blend, and care habits. No swimsuit should be treated as sun protection on its own; sunscreen, shade, and time management remain important, particularly during peak UV hours.

Fit tips for different body types

Fit tips for different body types are most useful when they focus on comfort, support, and function rather than strict rules. Start with your primary use case. A suit meant for lane swimming usually benefits from a secure, stable fit and straps that won’t shift. A suit meant for casual beach days may prioritize adjustability and comfort when sitting, walking, or playing with kids.

For a fuller bust, many people find more comfort in designs with wider shoulder straps, a supportive underband, and internal structure such as molded cups, underwire, or a higher-coverage neckline. If you prefer string-style adjustability, look for tops that combine ties with a firm band and sturdy stitching at stress points.

For those who prefer more midsection coverage, high-rise bottoms or one-piece styles with supportive lining can offer a secure feel without restricting movement. If hip comfort is a priority, consider bottoms with slightly wider side panels or softer elastic finishes, which can reduce pressure and improve all-day wearability.

For athletic builds, texture and construction can influence how a suit feels and fits. Ribbed or seersucker-like fabrics may feel more structured, while smoother, compressive knits can provide a more “held” sensation. Regardless of body type, it’s worth doing a quick movement test in a change room: raise your arms, twist at the torso, and simulate a swim stroke. A good fit should feel stable without relying on excessive tightness.

Care tips for long-lasting swimwear

Care tips for long-lasting swimwear make a noticeable difference, especially in Canadian conditions where a suit might see a mix of chlorinated pools, freshwater lakes, hot tubs, and strong sun. The biggest wear factors are chlorine, salt, sunscreen oils, heat, and friction from rough surfaces.

Rinse promptly in cool, fresh water after each use. Even a quick rinse helps reduce residue that can break down elastic fibres over time. If you can’t rinse immediately, let the suit air out rather than sealing it wet in a plastic bag, which can trap heat and odours.

For washing, gentle hand-washing with a mild detergent is usually the safest approach. Avoid bleach, harsh stain removers, and fabric softeners, which can damage elastane and affect stretch recovery. Don’t wring the suit; instead, press out water with a clean towel. Dry flat in the shade whenever possible—direct sun and high heat can accelerate fading and weaken fibres. If your routine includes hot tubs or heated pools, be aware that higher temperatures generally increase material stress.

Storing your suit also matters. Keep it fully dry before putting it away, and avoid leaving it folded tightly for long periods if the fabric has molded cups or structured elements. Rotating between two suits can help each one recover its shape between wears.

These trends—string adjustability, higher-cut leg lines, and tan-through concepts—can be approached in a straightforward, practical way. Paying attention to construction, lining, and fabric behaviour will usually matter more than the trend label, and good care habits help maintain fit and colour so a suit performs consistently across the season.
