Unless it's a verry complicated piece (like the sleeves on my florentine gown), I never use or make a pattern, I generaly cut directly into the fabric. But if you need to make yourself a patern for guidelines, here's the only thing you should have to worry about for this one; There's no waistline, it's all in one piece. The bodice measurements should correspond to yours if you want a good fit and than, from the armcye point to the hem, you go has wide as the fabric permits you to go. I've never seen evidence of gores on the front of these gowns and I've never seen any on the sides neither so, unless your textile is less than 56'' wide, you'll only need a generous one in the back.
