Or just slap a Driver on your waist and call it a day. :lol

Especially with Shinnosuke, You just slap the drive driver on your waist, wear a navy/indigo suit with white shirt and red tie, have the same hair, and draw a beauty mark on your right chin. For bonus points have someone as Kiriko.

I'm going to be Gandalf with a WizarDriver!

Heck you can go even easier and just put on casual clothing and if you have short hair, spike it a bit and you can be Ryou/Gills.

Or a speedo.

or...

Step 7. Give up, go to ebay then shell out hundreds/thousands of dollars to purchase the costume you were too unskilled/lazy to make yourself.

:p
