Normally when I order leggings, I have to order a size down to get the snug fit. As with all of my former pairs of Faded Glory leggings that are 95% cotton, I don't even think Walmart sells them anymore. The 95% cotton ones are so comfy and roomy and sturdy. These, which are only 57% cotton are terrible. I ordered a 2X, and couldn't even get them on. If you normally wear a 4X, you better get the 4 or 5X.
Depending on your point of view, these run true to fit, or run SUPER SMALL.
