Gosh, I don't really keep count. Some days I only wear a few pieces like one or two pieces, and other days I layer a lot. I don't really think it matters if you wear a lot of jewelry at once. If the jewelry type that you wear is delicate jewelry (dainty jewelry/small diamonds, that kind of style), then you can definitely layer or wear at least a couple of pieces at once, in my opinion. There are some days where I will wear a necklace, multiple rings, and two sets of earrings but all of the jewelry is small (low carat diamonds or under 1 carat), and more plainer, or delicate so I feel that it is okay to layer.
