This is a very basic instructional for making the dress I posted a while ago. There are no measurements in this instructional.
Take a large piece of fabric.
Fold the fabric in two so that both rough edges are on one side and the fold on the other.
Sew the rough ends together.
Hem the bottom and top of the tube of fabric.
Cut out 2 pieces of rectangle shaped fabric and sew down rough edges on the side you want to face inside.
Cut out 2 triangle shaped pieces of coordinating fabric. Sew the rough edges down of the side you want to face inside.
Sew straps onto dress. The triangle shaped ones go in the front and the rectangle in the back.
Finish off with a belt to give the dress shape :-D
