Now that living standards have improved, many people will donate clothes they don't wear, but some donated clothes don't reach those in poor mountainous areas. Instead, they are re-used by some black-hearted merchants to sell them on Taobao at low prices. Online shopping has become another important means for people to shop. Therefore, it is very easy to buy some old clothes online. I think we can start from the following aspects.

First, from the color of clothes, if it is recycled clothes, even if it is processed later, there will be some flaws. If you find that the color distribution of the clothes you bought is uneven, or the color of the whole clothes is dim, then these are old clothes after post-processing.

Secondly, judging from the trademarks of clothes, generally donated clothes are worn by donors for a long time, and there are few new clothes, so the trademarks of these clothes that have been worn for a long time will be stained with sweat and then yellow, and the specific contents of the trademarks cannot be clearly seen; Thirdly, from the sensitive points on some clothes, generally, clothes that have been worn for a long time will wear in some places that are often in contact with the skin, such as neckline, cuffs and hem of clothes, which are easily worn, so you can focus on checking these parts when you receive clothes.

In fact, there is a big gap between new clothes and second-hand clothes. Even if these second-hand clothes are processed twice, they still give people a different feeling. If you meet this kind of black-hearted businessman who sells second-hand clothes when buying clothes, you must not be soft-hearted. Complaints and bad reviews are necessary.
