    It may seem obvious to say so, but the best fabrics for a healthy skin are usually natural ones. Nonetheless, sensitive skin reactions are more frequently a response to chemical additives than to the actual fabric. There are a few precautions that you can take to protect your skin from toxins in clothing.

     

    Our clothes differentiate us sexually, safeguard our modesty, indicate social or occupational status and express our personal taste and style.
