According to the national regulations, the products with "three guarantees" do not include clothing, so it depends on whether the merchants have promised the "three guarantees" service on their own.

There is no legal provision for "three guarantees" products, and the conditions for return and exchange are generally stipulated by the merchants themselves. Generally speaking, if the trademark is still there and the clothes are in good condition, they can be replaced. You need to take the invoice, clothes and cut trademarks with you. But if the clothes are damaged or washed, they can't be changed.
