Here the hubby & I's costume from last year. It took minimal work to put together. I found the dress at a vintage clothing store for $12.00 and used lace remnants to make the mantilla. We bought the skeleton gloves at a costume store, along with the hubby's hat. And I bought some dingle balls to glue around the brim for dirt cheap. The rest was pieced together with things we already had.
Some other costumes from years past that were quick and easy to piece together for us were the Green Hornet & Kato and Rik & Vyv from the Young Ones. They were all put together with items we already had and thirft store and a few cheap costume shop purchases.
