I was hoping these fit me and they did!  I normally wear anywhere between a size 18W-22W in pants but in leggings, I have found that most of them are a size XL or a 1X.  So I was concerned and didn't know what size to order based on the comments left by other reviewers.  I actually ordered 2 different sizes.  For the black pair, I ordered a 2X and they fit just fine.  Very comfortable and not see through or thin at all with just enough stretch. I went up a size for all the colored leggings and ordered a 3X because they are lighter colors and I didn't want them to look as "skin tight". I also sized up in case there is any shrinkage after washing. Right now, they are comfortably fitted. Not too tight where you can barely breathe and not too loose where they are bagging down around your ankles and sagging in the butt.

I feel that the color on all of these are very good and so is the quality. I would definitely re-order.  My advice is order true to your regular legging size. I could've definitely taken a 2x in all of the colors.
