Aww, you all are too nice! Thanks for the nice comments.
Quick, revive Angie!
unfrumped, I'd say these might run a tiny bit bigger than the Leiths. These mediums are probably just a little bit smaller than the L in the Leiths, but a little wider through the knee and calf.
Una, the fabric is lightweight, completely opaque, and matte- sort of a silk crepe. The fabric is not as slippery feeling or flimsy as the Leith ones. I can see wearing them 3 seasons- they wouldn't be warm enough to wear outdoors in the winter. I definitely will wear them in the summer with sandals and a flowy top.
bj1111, I'm 5'6" and my inseam is around 30" or so for pants with flats. I'm an apple with rectangle tendencies, I think: thick through the middle with smaller hips and thighs in comparison to my waist.
I would say that there's plenty of extra room to accommodate larger hips or thighs in these pants.
Hope this helps!
