I'm allergic to many types of earrings. Since sterling silver is an alloy, I've found that department stores carry such a wide range of quality and the salespeople don't know about the brands, so I end up having to return many that I can't wear. For me, the best place to shop is Piercing Pagoda. I've never had trouble with their earrings and the quality is consistent. They also have a wide variety of styles for little girls.
