This classic Tiffany necklace goes with pretty much everything. I wear it with jeans, club gear and business suits. I think I even rocked it with a bikini once. Sometimes, I loop it around my wrist twice and use it as a bracelet when I want a change. My necklace is over 10 years old and I still wear it a lot (and still get compliments on it). Using a chemical silver cleaner and polishing cloth keeps it looking new. It's pretty thick so I think it can also double as a weapon during those rowdy bar brawls. (via Tiffany's)
