You have found your new lounge/yoga/whatever pants. As a big & tall woman I have one of two problems. Either the pants don't fit in the waist and are long enough, or the pants DO fit in the waist, but rest above my ankles. Worse? Leggings for bigger gals like myself tend to not be thick enough to hide the polka dots or flowers on your underwear. Perhaps you like people seeing your underwear design, but I'm not one of them. These pants are perfection. I am 6'1" and around a size 20-22 in regular clothes right now. I picked up the XXX version of these pants and they fit like a dream. I'd almost go so far as to say they might be a half inch too long if you go barefoot all the time.
I bought a gray pair and a solid black pair (dog owners beware, they are dog hair magnets). I recently started working from home and I was originally looking for something that was comfortable but wouldn't scare the neighbors...and also wouldn't require me to change if I needed to run to the store quickly. Some people don't care and show up at Wal-Mart in their snowman pajama pants, but I just couldn't bring myself to go full lazy bum.
These will fit. The material is thick enough to not be see through, the waist is comfortable, and they are long enough. I originally bought two pairs. I'm up to 6 pairs now. I never want to wear any other pants.
