It seems that when Piper wakes up in bed her hair is disheveled and she has no earrings on. After a brief flashback, it comes back to her in bed and suddenly her hair is more coiffed and she is wearing large pearl and diamond earrings.
However she in fact wakes up wearing just one earring, but because of the way the film was edited, it switches sides frequently.
