Table of Contents The short answer A swimsuit can lose its elasticity because of exposure to chlorine and salt water, sun exposure, improper washing and drying, poor quality fabric, and overuse. The result is a swimsuit that is no longer comfortable or supportive and has a greater chance of malfunctioning.However, there are simple steps you can take to prevent your swimsuit from losing its elasticity. Choosing high-quality swimsuits made with durable fabric is a great start. You can also extend the life of your swimsuit by rinsing it with fresh water after use, air drying it instead of machine drying, avoiding exposure to sun and chlorine for long periods, and rotating your swimsuits so you’re not always wearing the same one. Reasons why swimsuits lose elasticity Swimsuits are made from elastic materials such as lycra, stretch, elastane, and others. Elastic is a rubber material that eventually will degrade over time as well as when being exposed to chlorine, salt, and UV light. In addition to the above-mentioned reasons, there are multiple other reasons why elastic will degrade and your swimsuit will lose its elasticity. The main reasons for a swimsuit losing it’s elasticity are: Exposure to salt water and chlorine Sun exposure Improper washing and drying of swimsuit Low-quality fabrics Overuse Wear and tear You’ve wrung your swimsuit to dry Exposure to salt water and chlorine Both salt water and chlorine are strong chemical agents and can cause swimsuits to lose elasticity over time. Chlorine is especially damaging as it breaks down the molecules in swimsuit fabric, leading to a breakdown of its elasticity. This is the reason it’s so important to rinse your swimsuit in fresh water after each use. Contrary to many people’s belief it’s not to clean your swimsuit but rather to remove chlorine and salt as soon as you are finished using it. Sun exposure Just like with any other clothing item, swimsuits also experience sun damage. The UV rays from the sun break down swimsuit elasticity, resulting in a swimsuit that no longer fits well or is comfortable to wear. Improper washing and drying of swimsuit Washing and drying your swimsuit the wrong way can also lead to a swimsuit losing its elasticity. It’s important to use a mild detergent when washing swimsuits, as strong detergents can damage swimsuit fabric and elasticity. Also, it’s best to air-dry swimsuits instead of throwing them in the dryer. The heat from the dryer will cause swimsuit polymer molecules to break down faster, resulting in swimsuits that lose their elasticity more quickly. Low-quality fabrics Cheap swimsuits that use low-quality fabric will not last you very long. These swimsuits are not as durable, and the elastic in them may break down faster than swimsuits made with higher-quality fabrics. Overuse No matter how well you take care of your swimsuit, over time it will lose its elasticity. Wearing the same swimsuit over and over again will cause the elastic in the swimsuit to break down faster than if you rotate your swimsuit. Wringing your swimsuit to dry Another common mistake is wringing out swimsuits after rinsing them. This can cause swimsuits to lose their elasticity, as it causes the swimsuit fabric and elastic to stretch out. It might seem like swimsuits aren’t made to be out on the beach if they can’t handle salt, chlorine, or the sun. However, this is the nature of swimsuits. They’ll naturally lose their elasticity over time. You should not count on having the same swimsuit for years and years. It’s simply not realistic. If you want your swimsuit to last for as long as possible, you should get a chlorine-resistant swimsuit. This will last longer if you take good care of it.

It will deteriorate over time and instead of being flexible, it’ll instead become crunchy.

While it might not be the biggest deal, you should definitely consider getting a new swimsuit if your current loses its elasticity. There is nothing you can do to get the elasticity back and it will not get any better over time. The most noticeable downsides of your swimsuit losing its elasticity are: Decreased Comfort and Fit Reduced Support and Coverage Increased Chance of Wardrobe Malfunction Shortened Lifespan of Swimsuit Decreased Comfort and Fit When swimsuits lose their elasticity, they will lose some of the snug fit you had before. This can make it uncomfortable to swim in and might even cause swimsuit straps to slip off your shoulders or fall down. Reduced Support and Coverage In addition to the decreased comfort, swimsuits that have lost their elasticity won’t provide the same level of support or coverage you had before. This can be really uncomfortable, especially if swimsuit straps are slipping off your shoulders. Increased Chance of Wardrobe Malfunction When swimsuits lose their elasticity, there is an increased risk of wardrobe malfunctions happening. If swimsuit straps are slipping off your shoulders and swimsuit fabric is sagging in some areas, this increases the chance that something embarrassing will happen while swimming or at the beach. Shortened Lifespan of Swimsuit Swimsuits that have lost their elasticity won’t last as long as swimsuits with good elasticity. Over time, swimsuits with poor elasticity will start to deteriorate more quickly and may not even be wearable after a certain amount of time. How to prevent a swimsuit from losing elasticity? As we’ve seen, there is nothing you can do to undo the effect that lost elasticity has on your swimsuit. Once it’s started to lose its elasticity you should consider getting an upgrade. Since you can’t do much once your swimsuit already had begun to loosen it’s important to prevent this from happening in the first place.

This helps to remove chlorine, salt, and other chemicals that can weaken swimsuit elasticity over time. Wash Properly It’s also important to be mindful of how you wash your swimsuit. Make sure you are using a mild detergent that is specifically designed for swimwear and washing it in cold or lukewarm water on a gentle cycle. Air Drying Swimsuits instead of Machine Drying Instead of machine drying your swimsuit, allow it to air dry instead.

Avoiding Exposure to Sun and Chlorine for Prolonged Periods Exposure to both the sun and chlorine can cause swimsuit elasticity to degrade more quickly than normal. It’s best to avoid leaving swimsuits in direct sunlight or chlorine-filled water for long periods of time as this increases the risk of swimsuit elasticity being lost. Rotating Swimsuits to Avoid Overuse in a Single Suit It’s also important to rotate swimsuits if you have multiple swimsuits available so that you are not always using the same swimsuit over and over again. This helps prevent one swimsuit from becoming worn out faster than others, which can lead to swimsuit elasticity loss. By following these tips, you can help ensure that swimsuits retain their elasticity and last longer. While swimsuits may eventually lose elasticity over time, following these tips can help prolong swimsuit lifespan and keep swimsuits looking great for as long as possible.
