I have a skirt with a lot of fabric in it that gathers up at an (elastic) waist. I imagine my idea would wind up working much the same way. It looks fine and it’s comfortable and twirly! I do think it would be important to make the button-waist skirt out of a thin, ideally woven fabric.
Please post about how the skirt works out. I think the additional fabric will bunch up when the skirt is in its smaller mode, but I could be mistaken.
