3. Understand the fabric: These technological parameters directly affect the wearing experience

The fabric of a one-piece swimsuit is a central factor in determining wearing comfort, durability, and functionality. Many people will be confused by professional terms such as “chlorine resistance”, “quick-drying” and “UPF50+” when purchasing, in fact, as long as you master the core parameters, you can easily choose the right fabric. The following is a breakdown of the characteristics and applicable scenarios of several mainstream fabric technologies.
  • Chlorine-resistant one-piece swimsuit: suitable for people who often go to the pool to swim. Chlorine in the pool can corrode swimsuit fabrics, causing them to age, warp, and fade. The chlorine-resistant fabric is treated with a special coating that effectively resists chlorine erosion and prolongs the life of the swimsuit. Professional data: Ordinary fabrics will age significantly after about 10 times of use in the pool, while chlorine-resistant fabrics can last more than 30 times. Case: The swimming coach around me uses an anti-chlorine one-piece swimsuit all year round, and one can be worn for an entire swimming season, which is very cost-effective.
  • Quick-drying UPF50+ one-piece swimsuit: suitable for outdoor water activities. The quick-drying fabric can quickly drain the water after leaving the water, avoiding colds caused by wearing a wet and cold swimsuit; UPF50+ is the highest grade of sunscreen fabric, which can block more than 98% of UVA and UVB rays, effectively preventing skin tanning and sunburn.
  • Eco-friendly recycled nylon one-piece swimwear: suitable for environmentally conscious consumers. This fabric is processed from recycled materials such as recycled plastic bottles, which is not only environmentally sustainable but also as soft and elastic as ordinary nylon fabrics. Industry trends: In recent years, global environmental awareness has increased, and the market share of recycled nylon swimwear has increased year by year, with a year-on-year increase of 23% in 2024.
  • High Elasticity Nylon Spandex One-Piece Swimsuit: Suitable for various scenarios, especially sports scenes. The blend of nylon and spandex is highly elastic and wear-resistant, allowing it to fit snugly while allowing it to stretch freely during exercise without feeling restrictive. The common ratio is 85% nylon + 15% spandex, which has the best elasticity and durability.
  • Ice-like breathable one-piece swimsuit: suitable for hot weather. The fabric adopts a special weaving process, which can bring a cool feeling when it touches the skin, and at the same time has good breathability, which can quickly dissipate heat and avoid stuffiness and discomfort when wearing.

  • One-piece swimsuits cover the belly and look slim: In addition to choosing high-waisted and skirt styles, you should also pay attention to the tailoring design of the abdomen. For example, the abdomen adopts a pleated design and a waist drawstring design, which can effectively cover the belly. In addition, dark swimsuits are thinner than light ones.
  • One-piece swimsuit is anti-light: focus on the neckline, straps and legs. Don’t choose a neckline that is too low, unless it is supported by a chest pad or underwire; Choose a style that can be adjusted and widened to avoid slipping; Choose a slightly longer leg or a design with anti-slip strips to prevent shifting.
  • One-piece swimsuit with chest pad removable: This design is very practical and suitable for sisters with different chest situations.

7. Sourcing Agent Perspective (Yigu)

As a Sourcing Agent who has been deeply involved in the field of swimsuit procurement for many years, I recommend that when purchasing a Women’s One-Piece Swimsuit, you should prioritize the fabric and craftsmanship, which are the core of determining the quality of the swimsuit. From a purchasing point of view, chlorine-resistant, quick-drying, and high-elasticity fabrics are more expensive, but have better service life and wearing experience, especially for people who use them frequently, and are worth investing in. For brand selection, the quality control of professional sports brands is more stable, while the advantage of designer brands lies in the sense of design. In addition, it is recommended that you check the fabric test report when purchasing to ensure that the parameters such as sun protection and chlorine resistance are true and credible. If it is a bulk purchase, prefer suppliers with their own factories to better control costs and delivery cycles.
