I bought these to workout in. They have 2 issues for me:
1. They are see-through. Whether I was wearing underwear or not, you could tell either way. And these are meant for plus-size girls so we expect things to have to stretch further anyway so this was disappointing. Also when working out you are in different/more revealing positions than you maybe would be normally just sitting around. So if you wear these, make sure your fanny/front is covered.
2. The fabric doesn't stay up. And I don't think this is a sizing issue, because the waist-line cuts into my stomach plenty. But as soon as I started hitting the bags, the fabric slides down my hips and bottom. Even though these are pulled up above my belly-button when wearing them normally. (I had my boxing gloves on at the time, so that must have been pretty funny to see me struggle trying to pull up my leggings with no fingers between each punch.)
Overall, if these are meant for lounging or anything non-active they fit great. Be warned the material does create those little balls with friction (yeah, no thigh-gap) so they wear a little quick.
