When you are going to wash your swim wear, hand wash it do not put it in the washing machine because it will damage the swim wear and will lose its elasticity. I used to put the swim suit of my eldest daughter in the washing machine and the result, the swim wear is loose already. I know that her swim suits are not cheap, since she is on training I need a very durable swim suits but because of my being so careless, the swim wear now is damaged. Now I have to buy another swim suit for her to use this coming competition. Oh when should I learn?
