I bought the wig on eBay for about $20 after S/H, got the sportcoat, tie and pants from the thrift store for $5 total, and the cream based makeup at a Spirit Halloween store.
I taped stripes on the pants and jacket, using 1.5" masking tape.
I then used black fabric paint.
I was very pleased/surprised to see how straight the lines were when I removed the tape.
The final product.

I had a lot of fun dressed up as Beetlejuice. Countless people approached me and wanted to take a picture with me. I can't count how many times someone yelled "Beetlejuice, Beetlejuice, Beetlejuice!!!" at me!!! I will definitely bring this costume back in a few years!
