You can wear clothes without tags, but it is recommended not to wear them.
Each piece of clothing produced by a regular factory will have its own hangtag to indicate basic information such as size, washing method, ingredients, etc. If the clothes do not have tags, it is impossible to determine this information, and it is difficult to ensure the quality and safety of the clothes. In addition, if the clothes sold by the merchant do not have clothing tags, they do not comply with the over-the-counter sales regulations and are illegal.
Therefore, buy clothes with formal tags to ensure that you are buying products that comply with regulations and have quality assurance. If the source and quality of purchased clothing cannot be determined, it is best to wash it before wearing it to avoid potential health and safety issues. Wearing unhealthy clothing for long periods of time can lead to health problems such as allergies or infections.
