Translation:Shulchan Aruch/Choshen Mishpat/136

Paragraph 1- If one had his items swapped in the home of the craftsman, he may use the replaced items until the owner of the item comes to take it. This is only if the craftsman himself gave the item. If the craftsman’s wife or children gave the item, however, he would not be allowed to use it. Even if the craftsman himself gave the item, he would only be allowed to use it if the craftsman simply said, “here is a garment.” If he said, “here is your garment,” however, the recipient would not be allowed to use it.

Paragraph 2- If one’s items were swapped in a house of mourning or feasting, he may not use them. When the owner of the item comes, he must return the item to its owner even though he misplaced his own item. The same applies with a gentile washer who washes the public’s clothing if she were to bring a person's clothing that does not belong to him.
