Um...it was midnight and I had nothing better to do! And I wanted to get rid of my extra duct tape...Honestly, though, I don't know where I would ever wear this, so if you have an idea please tell me!
Put on the t-shirt, and start wrapping the duct tape around you - tight
After you've gotten the waist cincher shape that you'd like, cut yourself out of it
Cut off all excess fabric and even it out
Mark off spots for buttons and buttonholes
Sew on the buttons and cut the buttonholes
Try it on!
