I love haphazard jewelry - nothing too precious here - so I immediately lusted after Jessica Biel's Tom Binns Dumont necklace. This look is super easy to recreate with layers of chains and rhinestones found at a thrift store or vintage shop.
If you're more of a buy it than make it girl, a great jewlery line for this type of thing is Dirty Librarian, which can be found at Urban Outfitters.
