Chinese Character Question (with Pictures)

This year for Christmas I'm wearing a Chinese dress I got in Chinatown, Philadelphia, and I want to make a pair of earrings to go with it. I found these charms, but I don't know what the characters on them are. Actually, I don't know if these are even the right way up or around. Might somebody be able to tell me what they say? Bonus points if you know the name for the kind of dress I have.





Thanks in advance!
