So how do you overlay chiffon exactly?

[Cheekz]

So I have been doing all my research for prom and came up with my pattern for my dress that has a gathered bodice like this:


And my drawing:


...but....BUT...I only have the basic shell down, I need to figure out to overlay it with the gathered chiffon is their an easy technique I could follow to finish off the dress? Do I gather the overlaying fabric and sew around the base pieces shape in a ppillow-making style? Or is there an easier way?

Thanks In Adavance! Have a magical day!

Ok, so for the bottom, its easy.  Cut the chiffon the same as the fabric underneath, but sew it separately.  Get a rolled hem foot if you don't already have one.  Cut the chiffon on the bias--actually cut the under fabric on the bias too, it will drape nicer.  Also, a walking foot will make your seams nicer.   For the top, get some cheap stuff and practice on you dummy til you get it right.  Using a polyester chiffon, any ruching/gathering will be permanent once you iron it.
