Some unique ideas for homemade costumes include inanimate objects, characters from pop culture and trompe l'oeil looks. While the ideas may be unique, homemade costumes can be simple and inexpensive to put together, such as the bag of jellybeans shown in PopSugar.com's slideshow, "101 Costumes to DIY on the Cheap."
In addition to PopSugar, UpRoxx.com's slideshow, "40 Unique and Funny Pop Culture Halloween Costumes on a Budget" and Coolest-Homemade-Costumes.com contain a number of unique homemade costume ideas.
Rubik's cubes for both individuals and couples and a cat scratching post are among the inanimate object costumes.
Pop culture ideas range from the subjects of paintings to characters from books and movies, such as Rene Magritte's "The Son of Man" painting or a "Hitchhiker's Guide to the Galaxy" guy with towel and "Don't Panic" button.
Trompe l'oeil costumes are often humorous as well as eye-catching, as with the child alien abduction costume: The baby's head is the costume wearer's head, with the rest of the baby a doll's body attached to the front of the alien's black robe and the alien's face a hooded prop above the wearer's own head. Coolest Homemade Costumes shows how to create and put on the costume.
