There are good chances that one out of two cotton shirts is not made of cotton.
During the shopping, it is just the beginning of the health risk.
40% of clothing sold in stores does not meet the prescribed declarations, so instead of cotton, you buy polyester.
Also there is clothing color obtained from various chemicals that are banned in many countries because they are carcinogenic.
Experts say that the proof that the clothing is safe for health can be examined only in a laboratory. It cannot be recognized just by looking at it.
This is why you need to be careful when buying clothes. The only thing you can do is not buy clothes with a distinctive smell. If the piece of clothing you are about to buy has some specific smell it is most there is something wrong with it.
