I've heard of people wearing duct tape, but it seems that it would be very uncomfortable. It won't breathe well...at all...and if you screw up, you end up ripping layers of skin off with the stuff. Not to mention--that duct tape is for the off-season robot mods, not for wearing!
I would've liked to see some of the reactions you got, though.
Incorporating zip-ties into your clothing gets a lot more nerd points than this, I think...
