Petticoats

They don't make petticoats this size. And even though the edges are not supposed to be seen, they are usually lacy and it won't do to simply cut them short. But all the patterns I've seen for making them yourself are for ridiculous frilly flouncy ones for square dancing.

Do I look white cowgirl to you???!?!?

Real petticoats are for under skirts, so they fall nicely. And so your thighs don't freeze.

I examined halfslips at the stores, and modified one. It seems to work, but the waist crinkles a bit. I'll have to re-cut it so it fits better.
But it's the right length, and that's most important. I re-banded it at the waist after undoing, and also redid the seams with second stitching.
Shouldn't be cold anymore.
But I wish vanity fair made them extra small. Professionally made just looks better.
