Yet another fabulous DIY idea for all those extra chains and old necklaces most of us have laying around. If you don't have any laying around. Hit up your local thrift store. I assure you, there's plenty and usually on the cheap side! you're not wearing this on your skin so it can be the cheap stuff :)
grab those chains and make 2 short-ish necklaces with them. make them look grungy and messy. the thrown together look.
Attach them to the top holes in your combats or docs :)
