Generally, the return and exchange procedures of clothes need good labels and invoices before they can be returned and exchanged within 7 days. Since you cut off the label, it means that you have confirmed that the quality, style and other products of the clothing meet your purchase requirements. Ordinary stores can't let you return, and after cutting off the tag or trademark, the goods are in bad condition and can't be sold any more. Therefore, this aspect is also irreversible. Of course, you can bend the rules with the store and see if you can change it at a discount or offset some of the money for new clothes (but it is unlikely).
