If you're still not sure if you're going to dress up for Halloween or you just haven't had time to think of a costume, then this final installment of DIY costume ideas should provide you with some much needed inspiration.

You still have the weekend to get it together, and in the words of the formidable Dolores Huerta and Cesar Chavez, "Si se puede!" (Yes you can!).
