I'd go for the netting over a chiffon or light satin dress, if you could find netting with sparkles in it that'd work. Course now that I've looked at the pattern, the netting wouldn't work.
I'm guessing since this is for prom she isn't wanting the lolly pops on the dress and with that many pieces to the skirt that you are going to need something that flows, like a light stretch satin? A chiffon would work, but you'd have to do a lining under the chiffon. What about beading yellow lollypop designs or circles across the bottom? It looks like a fun project to do!!
