In private shops, it is more difficult to sell the same clothes after returning them because the number of purchases at one time is relatively small. Moreover, it is more difficult for him to return the money he received to you.

So I suggest that you discuss with the shopkeeper first, and whether you can exchange it for other styles of clothes in his shop, so that you can buy your favorite clothes without refund. It's best to have a similar price difference, or find a slightly higher price, and basically no refund or make up the difference.

If you don't like it, we suggest friendly negotiation. After all, you can't affect your life for one dress. We also told the shopkeeper that after this period of time, you will still go to him to buy suitable clothes and let him accept them emotionally.
