Hi there! This is the transform project which I'm so sorry not to took the photo along the process. I've ever didn't take a before photo but you can imagine any 2 shirts as material for doing this.
You have just to make sure that two collars from both shirt can wrap around your waist. What I have done is use the seam ripper to take apart of collars from shirt and use them as waist band. I cut the lower part of shirts to make the skirts part, connect them at their button plankets. Then gather the skirt and sew it to the ex-collars waist band. Voila! Got the cool skirt.
