Ck underwear of Chengdu Outlets has not been taken off the shelves yet. Can I change it?

If it is clothes, according to the new Consumer Protection Law, as long as it is not worn within 7 days, it will not affect the secondary sales of the goods, and consumers have the right to request a return. But underwear can't.

If the clerk refuses, you can communicate with their store manager or person in charge and clearly explain the reasons and requirements. If the merchant still refuses, you can ask the industrial and commercial department to intervene.
