SOS!

I've finally figured out what I want to make for my eldest daughter's First Holy Communion dress. Basically, a child's version of this folkwear pattern. I've got some amazing dupioni silk and embroidered chiffon that would knock this out of the ballpark, but I'm at a loss for the ~pattern~ to make it happen. If anyone would know where to find such an animal, the gang here would. Current Big Three patterns are of no use to me since there really isn't what I want in their current catalogs (grrrr).
