Add a ruffle if you're so inclined

Today while sifting through my fashion email spam (I have a separate Hotmail account dedicated to this kind of stuff), I came across these pants - the foldover pant with ruffle by So Low. They remind me of the Burda yoga/lounge pants (11-2007-122) that I made recently. What a fun idea to add a ruffle to the waistband. I'd love to see someone try this...
