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.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
