I ordered up one size to make sure I had enough room in the ankle area and stomach. These leggings fit very well and to my surprise, they really are breathable! I wore yesterday under a light skirt and the temp was high in the 80's and I was comfortable. No sweating and sticking to legs. I would say they are a notch more than my panty hose. I think these would be perfect in colder weather as well. I ordered in navy blue and black. I haven't washed them yet. If they shrink I will have room. If there is no shrinkage, I will order more in my normal size 3X.
