You can wear underwear without a brand on the label.

If you find that there is no brand on the underwear label, you can wear it after confirming that the workmanship and fabric of the underwear are suitable for direct skin contact. At the same time, it is recommended to wash and dry underwear before wearing it to maintain hygiene and comfort.

However, it is worth noting that underwear without a brand may mean that they have not passed quality inspection or certification, so their quality may be at certain risks. Therefore, when buying and wearing underwear, it is best to choose products with clear brands and manufacturers to ensure their quality and safety.
