When purchasing swimsuits, you can touch them with your hands or refer to the ingredient content table of the materials to see how they are made. A good swimsuit fabric is soft and elastic, with relatively dense patterns and exquisite cutting. It is sewn with elastic threads and will not be stretched or broken due to exercise. When trying on, follow the principle of fit and comfort. If it is too large, it can easily catch water, increase the burden on the body and resistance during swimming. If it is too small, it can cause strangulation on the limbs and cause poor blood flow.

1. Fabric and structure. It is best to choose elastic fabrics with a spandex content of more than 15%, so that the swimsuit can stretch and contract freely with body movements; When swimming in a swimming pool, it is important to pay attention to the adaptability of the fabric to the chlorine molecular content of the water in the pool. Currently, swimwear made of the most popular three-dimensional elastic fabric in the world is most suitable for use in low-temperature water or swimming. Because this fabric has a lot of hollow space, it is easy to maintain body temperature. Try to buy as little or no imitation so-called "imported spandex high elastic fabric" as possible. One is that the spandex content of clothing fabrics is generally around 15-20%, and the other is that imitated fabrics have poor elasticity after being washed into water due to variations in composition.

2. Workmanship and safety. Due to the fact that swimwear is a practical sportswear with strong tensile strength, it is best not to choose styles with more stitching. When there is a lot of exercise, it is easy to cut the thread from the joint. At the sewing seam, three stitches and five stitches are the basic, with three stitches and six stitches being the most secure. The elasticity of the thread should be consistent with the stretching degree of the fabric. It is best to choose a beach outfit series with pleated lines, which not only looks beautiful but also has stronger elasticity and stretch.

3. In terms of hygiene, the silk covered cotton swimsuit has the advantages of a smooth and bright surface made of chemical fiber fabric, while the inner layer is made of pure cotton, which is non irritating to the skin and is particularly suitable for people with skin allergies to wear. The crotch of a swimsuit should be lined with fabric, and swimwear with lining should have a longer lifespan. Wash and sun before use.

4. In terms of safety, when swimming in natural rivers, beaches, and deep water, one should choose swimsuits that have a significant color difference from the water. In case of danger, the goal is more obvious and convenient for first aid.

5. Body shape and skin color. For those with oversized breasts, it is suitable for a wide shoulder V-neck swimsuit; For those with a small chest circumference, try to avoid strapless swimsuits as much as possible; A swimsuit with a flat chest that is suitable for decorative pleats on the chest; For those with a large hip circumference, it is advisable to choose a super short swimsuit; For those with a thick waist and a lack of attractive curves, a combination swimsuit can compensate for the shortcomings and provide excellent results after wearing; The legs should be thick and short, so choose a style with legs cut high and sharp corners at the bottom; Long and slender legs lack a sense of symmetry, and flat legged swimsuits are the preferred choice.
