Strung Out: Put a random item on a chain - like an antique key, old subway coin, or a ring that doesn't fit - and wear as a necklace.
Scarfing: Loop a scarf through your jeans as a belt. Or wrap a thin scarf around your head as a headband or around your wrist as a cuff.
Watch It: Hook your watch through a belt loop, a la the pocket watches of yore.
Piled Up: Wear all your bangles instead of just a demure few. Wear several delicate-chained pendants at once. Wrap a pearl necklace several times around your wrist as a bracelet.
Recycle: When your favorite tights get holes in the toes, cut them off to make leggings. If your coat loses a button, use a sparkly brooch to keep it closed instead.
Get Stoned: Every woman has a few rhinestones floating around. Use a bit of cosmetic glue to secure one to the side of your eye or into the hollow of your neck in place of a necklace.
