Faded Glory warm winter patterned Leggings

Reposhing this item I purchased from @ana101p. I have 4 of these patterned warm festive holiday patterned leggings now in the same size, Medium. I live in the 2 that fit me, I can work sleep live in them all day. However, 2 of them are constructed differently than the other 2. This pair here is one of the 2 that is much smaller than the other 2, and doesn’t fit me! The brand must have changed their sizing or material from year to year. Therefore I am listing as a Small despite the medium tag
