Plus Size High Waisted Fleece Lined Leggings

I was gifted two black, one purple, one blue, and one red, all labelled the same 'plus size'. Despite them all being labelled as the same size, I found that the coloured ones fit great while black ones were very snug.
I absolutely love the coloured ones, even though they begin to pill after one day of use. They are warm and fit great, even when bending down. When putting on the first black one, I found that I could barely get it over my derriere. I put my thumb through the fabric trying to put it on and made a huge hole. I was much more careful putting on the second black pair, but when I checked myself in the mirror, there was a hole in the exact same spot. I think it's just a weak point in the design. If you have a large tushy, perhaps consider a different set of (black) leggings.

Wish there was more stretch and larger sizes.
