Welcome to the world of jewelry as influenced by S & M. Actually, these are head pieces designed by Carlos Diez for the Spring/Simmer 2008 Pasarela Cibeles show in Madrid.
What else can you call these wild creations? Wearing this kind of jewelry requires special thought. First, stay away from airport security, second, if you have phobia about braces, stay away. Third, if people pointing at your would give you issues, I wouldn't recommend this.
