First, KnightsWhoSayKnit, I love your name.
Second, yes, about that shape, but I need to do it without a gather, as there will be a band of color around the neckline. (definitely keeping the gathered pattern though, that looks really nice :-) my current design sketch can be found here:
I like my general design, but I think a sweetheart neckline would look better and fit the fire theme better. Nifty point at the center and all that. :-) I'm mainly worried about making sure not to do the inward curves so severe that the neckline flops.
