How much fabric you need depends on the measurements of the person who will wear the dress, on the width of the fabic you choose, and on the pattern of the fabric, if any. What I would suggest is to go to a fabric store that also sells patterns (taking with you the bust, waist, & hips measurements of the person who will wear the dress). Page through the pattern books and try to find a pattern similar to the style of dress you want to make. Then consult that pattern for fabric measurements and fabric type suggestions.
