One way to stop contributing to the inevitable waste is to get crafty and make your own costumes out of things you have lying around the house. Here are a ten unique, inspiring costumes made out of recycled junk that are sure to impress on Halloween.

4. Game of Thrones Illusion

Serious Game of Thrones fans will dig this getup.

This particular illusory costume was made from cardboard boxes, vertical blinds and palm fronds found in a dumpster. The jacket was fashioned out of old fabric, and the fur trim, pants and boots were picked up at a thrift store. The sword was an old prop the creator had on hand.
