If it helps at all GLC, I buy a lot of my skirts slightly on the larger side because I do have a bigger butt and thighs than the rest of my frame might suggest. So, they end up sitting low on my waist. With a sweater one, you can't really tell though. Perhaps that's something you could do with skirts, too. I find that a lot of skirts don't have to fit as "just so" as pants do.
