Learn about material
In the swimsuit world, the polyamide and elastane were the most popular and sold material. The elastane brings elasticity to the swimsuit, so it is easy to fit in and comfortable to wear. The only problem with this material is that it doesn't really resist to the chlorine and salt well. Your bikini loses his elasticity and tend to distort with time. It is not a problem if you go to the pool once every six months but if you swim every week, it is recommended to choose another alternative.
Few years ago, polyester material came to the market. This material can take a little longer to dry and be a bit less elastic but it does resist very well to the chlorine et don't get distorted with years that's why we choose to use this material for our products.
When you get out of the water, we recommend you since with clear water. Do not put in washing machine. Do not use toxic products on it, we recommend soap if you want a more complete wash. Avoid to use dryer and to twist your bikini to dry it, you can use a towel to dry it in ;)
