Sooo red fabric and the Mina Gown

This is the last day for the silk sale at Fabricmart, they have this for 10 bucks a yard: http://www.fabricmartfabrics.com/Fire-Red-100-Silk-Satin-Organza-53W.html

What would the minimum yardage be for a Mina inspired gown? I say inspired because a silk satin organza would behave very different from the fabric the movie gown is made from, but it could still look very neat.
