Costume Jewelry for Costume Purposes

There are instances or events like family or friends gathering, promenade, party, Halloween, even Christmas party and alike need costumes or like a costume party. Now, one have to find a costume jewelry to blend up with the costume to fit and look good. You do not to look like you only have one accessories, don't you? If a person is a party one, I bet she has many costume get-ups and costume jewelry or maybe all are genuine. :) I love collecting costume jewelry though I seldom use it.
