Start out with some fabric, jersey preferably. There are only two pieces to this shirt, a top piece and bottom piece. The top piece is at has to be larger than the largest part of your torso. I went with ten inches longer with the width of the fabric. The length of the top part is from the shoulder to the top of hips or a little longer.
The bottom piece's width is about 6-8 inches and the length is your waist measurement.

You're going to want to sew the fabric you cut out into tube shapes so sew them along the width which is marked in the previous diagram.

take a break from the sewing for a minut e. Take the leftover fabric and cut out three half inch wide strips that are at least 15 inches longer then the measurement above your bust. Take those three strips, tie a knot on one end, and braid them. When you are braiding it, the strands will start re-braiding at the bottom, make sure you separate them.Tie the other end of the string when you are done.

Back to sewing! Sew a casing along the top side of your top tube piece that is wide enough to pull the string made int the previous step through, mine was about a half inch wide. after sewing the casing, cut two small holes through one side of it on the middle of the front of the tube (does that make sense?) and attach a safety pin the the string and pull it though.

And you're done! Now you have a shirt you can wear 10 different ways. Thank you for your time!
