Kate Hudson's amazing crochet shorts from Something Borrowed

Has anyone tried to make these? I found the pattern for the circles and pineapples. I don't think there is a "real" pattern out there for the whole thing. The waistband is a piece of cake. I can't find the filler patterns and need ideas for: Attaching to the waistband, shaping for the shorts pattern (ie: crotch and curved areas) HELP!
