Most of the labels on the collars of clothes are made of nylon, which affects the appearance. The specific method to remove it is as follows:
Put the label of the clothes firmly in one hand and flatten it. With the other hand, flatten the label with the same force and pull it out, and ask others to help along it. Cut the tag closest to the clothes directly, making sure that the remaining part of the tag cannot be seen. If you pull it straight and cut it properly, the remaining tag will pop into the clothes as soon as you let it go.
Try using high-temperature water to make the label softer, use a needle to separate the thread, remove the label, and then sew it up. Of course, this approach is very risky, and the prerequisite is that your needlework must be good, otherwise it will look ugly.
Buy clothes without trademarks on the back of the neck. There are many regular clothes now. The trademarks are on the side, which can prevent the clothes from being worn backwards and make it easier to dry the clothes. It is safe and comfortable to wear.
