First start with two shirts. They can be the same color or different colors, your choice!
Cut off the bottom half of one shirt under the bust line. These will be your pleats
Cut that piece in half
Leave the first piece the same size, and then cut pieces of different lenths. make sure there are two sides, because we are goign to sew them together so it has more volume.
Take t he pieces and sew right sides together, then flip them right side out. Lay them on your shirt to see the look you want, then sew them on at a time, laying another strip on top every time.
Done. Simple easy accented shirt. Not my favorite, but it does jazz up a plain shirt.
Now for the shirt you cut up. I got this gray shirt really cheap because it was huge, and had this weirdo hole right in the center of the back. Who does that? Cut the bottom of the second shirt also at the bust line.
Sew Right sides together all the way around and now you have a to toned shirt! I made mine a little tighter on the sides on the gray portion, because it was looking like a maternity shirt. If you actually want a maternity shirt this is a great one!
