One huge tshirt, some scissors and a freezer paper stencil. I took a clearence Walmart 4x tshirt and restyled it into this cute tunic. It was super easy. I just cut off the sleeves and the neck and threw it on the dressform pinning it to fit. Used the excess fabric to make bias around the arm openings and the neck and shirred the waist. I just felt like it needed something so I freezer paper stenciled a white chevron. Perfect. Cute new dress in under two hours and less than $4! Love it.
Here is a tutorial on stenciling with freezer paper, in case you don't know how!
