Chi: Lol. That works too.
I think this will call for a specifically-made petticoat to ensure maximum and even poofage. And I foresee this skirt taking much more time than I'm assuming it'll take, as I've already spent a good 6 hours on it total (sewing pleat-thingies at the waist and pleating the ruffles), and it doesn't even have shirring or a zipper yet.
Don't mind the janky Slytherin emblem; that's a reject shirt patch I made years ago while trying to figure out how to use printable fabric correctly. I just wanted to get an idea of how it will kinda look when it's all done...
