I found an old shirt of mine and made it into a dress for my daughter. Sorry the pictures are so blurry. I took the first few with my phone because my daughter was sleeping at the time and my camera was in the room she was in.
I started with this....
Cut out the pieces of the shirt you would like to use..
Cut out 12 pieces of long strips and braid them together so you have 4 strips.
Sew the two pieces together.
Pin the straps in place.
This is the front..
This is what the back looks like.
