Swimwear trends: string swimsuits, high-leg bikinis and tan-through designs

Each summer brings a fresh wave of swimwear inspiration, and the current season is no exception. Designers and high-street brands alike are embracing a mix of nostalgic throwback styles and fabric innovations that prioritise both aesthetics and function. Knowing what is available and how different styles work can make the difference between a swimsuit you wear once and one you reach for all summer long.

High-leg bikini styles making a statement

High-leg bikini styles have made a significant return to mainstream fashion, offering a silhouette that elongates the legs and flatters a wide range of body shapes. Originally popular in the 1980s, this cut has been reinterpreted with modern details such as ruching, minimal side coverage, and bold colour blocking. Retailers across the UK are stocking an increasingly wide variety of high-leg options, from sporty one-pieces to two-piece sets with adjustable ties. The style works particularly well in solid tones or simple prints, where the focus remains on the overall shape rather than the pattern.

The string swimsuit comeback

The string swimsuit comeback is one of the most talked-about moments in recent swimwear fashion. Minimal in coverage but bold in presence, string bikinis and one-pieces with thin straps have been embraced by a new generation of wearers who value freedom of movement and reduced tan lines. The appeal of the string style lies in its versatility — straps can be tied differently to adjust coverage and fit. While the look is undeniably daring, many brands now offer padded or structured versions that maintain the aesthetic while providing more support. For UK shoppers preparing for holidays abroad, these lightweight pieces also pack down easily and take up minimal luggage space.

Tan-through swimsuit fabrics explained

Tan-through swimsuit fabrics represent one of the more practical innovations in modern beachwear. These textiles are woven with a micro-perforated structure that allows UV rays to pass through the fabric, enabling an even tan without the need to constantly reposition straps or remove the swimsuit entirely. Brands offering tan-through swimwear typically use specially treated polyester blends that maintain colour, shape, and durability despite the open-weave construction. It is worth noting that tan-through fabrics do not replace sunscreen — UV protection is still essential, and wearing SPF underneath or on exposed skin remains important. These styles are particularly popular among swimmers who prefer a single, even tan line throughout the day.

Adjustable swimwear fit for every shape

One of the most practical developments in contemporary swimwear is the increased focus on adjustable swimwear fit. Brands are now designing pieces with multiple tie points, removable padding, and convertible straps that allow the same garment to be worn in different configurations. This means a single bikini top might function as a halter neck, a bandeau, or a cross-back style depending on how the straps are arranged. For UK shoppers who have struggled with standard sizing, adjustable designs offer a more personalised fit without the need for alterations. Many sustainable swimwear brands in particular have invested heavily in this feature, aiming to extend the lifespan of each piece by ensuring it adapts to changes in body shape over time.

Swimwear care tips to extend longevity

Following simple swimwear care tips can significantly extend the life of any piece, regardless of the style or fabric. Chlorine from swimming pools and salt from the sea both degrade elastane and nylon fibres over time, causing swimsuits to lose their shape and colour. Rinsing your swimwear in cold, clean water immediately after use is one of the most effective ways to preserve its quality. Avoid wringing out wet swimsuits; instead, gently press out excess water and lay flat to dry away from direct sunlight, which can fade colours and weaken fibres. Machine washing is generally not recommended for swimwear — hand washing with a mild detergent is the safer option. Rotating between two or more pieces rather than wearing the same one every day also allows the fabric to recover its elasticity between uses.

Swimwear today covers a far broader range of styles, fabrics, and functional features than in previous decades. Whether you are drawn to the sleek elongation of a high-leg cut, the minimalist appeal of string silhouettes, or the practical benefits of tan-through technology, there is a well-crafted option suited to your needs. Investing a little time in understanding the construction, adjustability, and care requirements of your swimwear ensures that your chosen pieces remain looking their best for many summers to come.
