你说的是网上购物吗?
你可以先用相机拍下质量问题的细节,然后和卖家协调,要求他给你补偿或是退换。一般来说来回的邮费都几十了,问题不大的话,让他给你退一些款,找裁缝修补下好了。假如卖家态度恶劣,就投诉他要求赔付。
Are you talking about online shopping?
You can take pictures of the quality problems with your camera, and then negotiate with the seller to ask him to compensate you or return or exchange. Generally speaking, the round-trip postage is several dozen yuan. If the problem is not serious, ask him to refund some of the money and find a tailor to repair it. If the seller has a bad attitude, complain to him and ask for compensation.
