For at least one of my formals (the Kiwi equivalent of prom) this year, I'm planning on makng a dress similar to this:

I plan on it being pretty much the same, except without the puntucks and rick-rack on the bodice. So, does anyone know of any patterns with a similar shaped bodice? Or any patterns that are similar in general?
If you can help, I'll be forever in your debt. Thank you in advance!
