So, this instuctable is basically my take on this instructable (credit go where credits due), more exactly it's done by my leftovers from making that instructable and from making this insttuctable of mine. You should check them both out.
This is a cheap and fairly easy way to make a dress and is perfect if you have some scrap fabric from other projects.
This is what you will need:
-The bottom half of a tanktop
-Some fabric in the lenght of your choosing, you should be able to wrap it about one and a half time around yourself
-A sewing machine
