1.Formaldehyde is used for fixing color and anti-crumple in the process of clothes printing and dyeing. Except quality, another difference between authetic products and copycats is the presence of formaldehyde.
As we all know, formaldehyde is toxic and harmful to our body, which can trigger disease like cancer. Therefore, we have to wash the newly-bought clothes before wearing.

2.I had seen a funny picture posted on social media. Someone's upper-body became totally black after wearing an unwashed new T-shirt for a whole day. LOL. When he took off the T-shirt at night, It looked like another T-shirt being glued on his body. This story sounds interesting. However, if the man was allergic, he would probably be infected by dermatitis. And if the dermatitis is dealt with delay, it would cause bacterial infection or lesion, which is bad for health.

3.Children's clothes : Parents should pay more attention when they buy clothes for their kids. Children are weak in immunity. Dark color clothes are easy to fade, so they should try to buy undertint and unprinted clothes for their kids. Meanwhile, there is an advice for buying children's clothes. Parents can have a look at the tags, If the clothes is classified as A, it would be safer and the formaldehyde will be less.
