I have the Lena skirt. It's a small, and it fits well. Usually, I wear an xsmall petite (size 2) in regular clothing and I wear Ibex xsmall in tops. But I have found the Ibex stuff to run much smaller in the bottoms, or at least they are not cut to fit someone with a body like mine. I am 5' 1" and I am very slim on the top and waist. My hips and thighs are within the size proportions that Ibex has on its website, but on the outer edge of the measurements. When I tried on the x small pants, they would not get over my calves!
