My brother's wife has many high quality earrings. Some of them are gold and silver, with little diamonds or sapphires. She gets them for
free.
That's because they are mismatches. People often lose one earring and then they have no use for the other one. All of her friends know that she does a mix and match thing. She has so many, that it's always easy to find two that go together well, although they are not an exact match.
Just a simple little trick, that allows her to have quite upscale jewelry on no budget at all.
I don't think this would work with shoes or dentures, but it's working quite well with earrings. Her friends also give her stray necklaces and broken bits of jewelry that are cobbled into other attractive items.
I will ask for a picture, the next time I see them.
