These are wonderfully soft and thick. I sized up one size, and the fit is a little closer to narrow joggers than leggings on me. I'm totally OK with that, and will wear the heck out of them on cold days. I would not size up in these if you want them as leggings, though, unless you are at the top of your size range. I'm 5'7", 34" waist and 41" hips and wear L in the Stella, which have plenty of room in the waist. XL in Nora stays up fine, though, and are super comfy. I'd love to see these come back!
