Duck a la tape
So this is my duct tape creation for my final year of high school. I based my top on a bra and a 3-pack of really thin large white tshirts. My date broke his big toe a week before prom so his shoes are really sandals with a faux top made of a small white tshirt. The rest is either $1 a yard fabric from Walmart or actual clothing items.
