Janet and Angie, thanks for your response! According to the Tildon size chart on the product info page, I should order a XS going by the waist measurement, but order a S if going by the hip measurement. So that's where it gets confusing. I read somewhere that you should always fit the larger part of your body. If so, then perhaps Small is the way to go?
Gigi, I have not tried knitted tube skirts by other designers but shall try it. Hopefully the fabric of the Tildon skirt is substantial and the sides are tapered enough so that it will not shift around when I stride.
Joyce, good luck with your skirt, too! Would love to know how sizing up works out. The black and white color palette goes with everything, and the mismatched dots are unique. I see a lot of potential with this piece and it will go with many things that I already own!
