I don't know if you want to try this, but I made one for a Halloween outfit and it worked great. It's practically sewing free so that was also a plus, the only thing you have to stitch is the elastic at the end of it all.
What I did was bought the colors of tulle I wanted and then took a waist measurement. After that I cut the elastic band to fit and started tying on the tulle. You will have to cut the tulle into strips first, in my case I just laid it down and cut it with a rotary blade every so many inches. You tie it in the middle of the strip you cut. Here is what I ended up with-
The fuller you want it the more tulle you tie on. Also, you can cut it as short as you wish, make the edges more tulip like or jagged, whatever you want really. She won first prize by the way, so I thought it came out really well.
