2025 Handbook for Thong Bikinis & Minimalist Sustainable Swimwear in the United States with Inclusive Sizing

The American swimwear industry has undergone a significant transformation, with minimalist and thong-style bikinis emerging as mainstream fashion choices rather than niche preferences. This shift reflects broader cultural changes toward body positivity, environmental consciousness, and personal expression through fashion.

What’s driving the 2025 trends in minimalist and thong swimwear

Several key factors are propelling the popularity of minimalist swimwear designs. Social media platforms have normalized diverse body types and swimwear styles, while Gen Z and millennial consumers increasingly prioritize sustainability and ethical manufacturing. The rise of body-positive movements has created demand for swimwear that celebrates rather than conceals natural body shapes.

Sustainability concerns drive many brands to adopt recycled materials, particularly recycled polyester made from ocean plastic waste. ECONYL regenerated nylon, created from fishing nets and fabric waste, has become a popular choice among eco-conscious manufacturers. These materials offer durability and performance while addressing environmental concerns.

The minimalist aesthetic aligns with broader fashion trends favoring clean lines, neutral colors, and versatile pieces that transition seamlessly from beach to street wear. Many consumers appreciate the reduced tan lines and enhanced comfort that well-designed minimal coverage provides.

Brands and US online destinations to check (what to look for)

Several established and emerging brands specialize in minimalist and sustainable swimwear. Solid & Striped offers classic cuts with modern sustainability initiatives, while Summersalt focuses on inclusive sizing and eco-friendly materials. Girlfriend Collective extends their sustainable activewear expertise to swimwear, using recycled materials throughout their collections.

Direct-to-consumer brands like Andie and Cuup have gained popularity for their size-inclusive approaches and quality construction. For luxury options, brands such as Jade Swim and Hunza G offer unique textures and premium materials, though at higher price points.

When evaluating brands, look for transparency about manufacturing processes, material sourcing, and sizing methodologies. Reputable companies provide detailed size charts, fabric composition information, and clear return policies. Customer reviews often reveal insights about fit, durability, and actual sizing compared to listed measurements.

Where to find truly inclusive sizing and what those labels mean

True inclusive sizing extends beyond adding XL and XXL options to existing size runs. Comprehensive size inclusivity involves designing patterns and cuts specifically for different body types and proportions. Brands practicing genuine inclusivity often offer sizes from XS to 4XL or beyond, with corresponding adjustments to proportions rather than simple scaling.

Size labels can vary significantly between brands, making understanding measurements more important than relying on letter sizes. Many inclusive brands provide detailed measurement guides covering bust, waist, hip, and torso length. Some companies offer “sister sizing” where the same style is available in different proportions for various body shapes.

Look for brands that showcase diverse body types in their marketing and provide specific fit guidance for different sizes. Companies committed to inclusivity often invest in extensive fit testing across their size range and offer detailed styling advice for each size category.

How to search US online stores for thong/cheeky/string styles in extended sizes

Effective online shopping for minimalist swimwear requires strategic search techniques. Most retailers categorize swimwear by coverage level, with terms like “minimal coverage,” “cheeky,” “thong,” and “string” indicating different degrees of exposure. Use specific search terms combined with your size requirements to narrow results effectively.

Filter options typically include size range, price, brand, and style categories. Many sites allow filtering by specific features like adjustable ties, removable padding, or sustainable materials. Advanced search functions on sites like Nordstrom, Revolve, and ASOS enable combining multiple criteria for targeted results.

Consider using size-specific search terms like “plus size thong bikini” or “extended size minimal coverage” to find options specifically designed for larger sizes rather than scaled-up versions of smaller sizes.

Prices, rates, or cost estimates mentioned in this article are based on the latest available information but may change over time. Independent research is advised before making financial decisions.

Practical fit and shopping steps to reduce returns

Successful online swimwear shopping requires careful preparation and realistic expectations. Start by taking accurate body measurements using a flexible measuring tape, measuring over undergarments similar to what you’d wear with swimwear. Record measurements at multiple times of day, as body dimensions can fluctuate.

Read size charts carefully for each brand, as sizing varies significantly across manufacturers. Pay attention to fit models’ measurements when provided, and look for customer reviews from people with similar body types and measurements.

Many brands offer virtual fitting tools or detailed fit guides specific to different styles. Take advantage of generous return policies by ordering multiple sizes when uncertain, keeping tags attached until you’re confident in your choice.

Consider the intended use when selecting styles and sizes. Swimwear for active beach sports may require different fit considerations than pieces intended primarily for lounging or tanning.

The evolution of minimalist and sustainable swimwear represents a significant shift in both fashion and consumer values. By understanding current trends, identifying inclusive brands, and employing strategic shopping techniques, consumers can find swimwear that aligns with their aesthetic preferences, body type, and environmental values. The key lies in research, patience, and willingness to invest in quality pieces that offer both style and sustainability.
