I made two muslins based on a tried and true straight skirt pattern. I built up the waist to be a raised waist and adjusted the hem/back sections. Here's the first one, which has a flounce all around the hem and two tiers of flounces at CB.
And the second version, which has a vent at CB and a long flounce that begins just about an inch below the natural waist.
Sometimes I get so married to a concept that I can't objectively see whether it's even a good idea or not. I would welcome any feedback/reactions -- positive or negative!
