(Photo: Getty Images) If you want to show up at a Halloween party dressed as a character everyone will know -- but you don t have a ton of cash to blow -- try making your own outfit. Instead of buying $50 to $100 worth of plastic junk that you ll throw away on November 1, head to the thrift shop and craft store. For under $20 and weekend s worth of time, you can turn yourself into Lady Gaga, a Twilight vampire, or any number of movie and TV characters.
