I have found these leggings to be warm, extremely comfortable and soft while holding their shape.  Being the size which is on the border between the One Size and the Plus Size, I was unsure of which to order, but in light of previous reviews and the 8% spandex content, decided that the One Size was probably sufficiently stretchy.  Using these much as pantyhose with a black skirt and boots to keep legs and knees warm when cold winds blow, these plaid leggings are a fashionable addition, especially when the outfit is also paired with a red buffalo-checked jacket.  Another use for the leggings could be as part of pajamas, in which case some who are also on the border between sizes may wish to size up for the fit to be similar to that of pants.
