Persephone.  Goddess of the underworld.  Ooh, groovy.  A lightweight, unlined broadcloth skirt with flow and flair. Back corset style lacing will allow for 3 inches to fit each size, so even if you are close, you'll get an excellent fit.  Has 2 drawstrings at the back and you just slide the material up the drawstring to create as much bustle as wanted, or leave as is for an A-line victorian skirt with ruffles all along the hem.  Wear with a petticoat for fullness, or on it's own.  Satin is formal and elegant, black and white pinstripe adds slimness and length,  solid black is historical and classic, brown with khaki is an airship aviatrix's dream. High waist, side zipper.  Available like this, full length, above the knee (that's the Mini) and below the knee (Persephone Mid-length).
