Be Elderly
Another easy last-minute costume idea that you should always keep in mind is dressing like an older version of yourself. This is typically very easy because you can raid a family member’s closet, or head to a second-hand near your home store to find the perfect outfit. Look at this example.

Do you know who this is? It’s none other than Heidi Klum! Isn’t her costume amazing? Of course, she had some professionals to help her with the makeup, but it shouldn’t be too hard to add some wrinkle lines to your face. Then grab a cane or walker and you are all set to party!
