I am a true 2x and have been dreaming of owning these denim leggings! So when they went on sale, I jumped on it! I bought both the 2x and 3x for size comparison bc I had a feeling they would run small. When I opened the pkg for the 2x, I didn't even bother to try it on. The thick pull on waistband has very little stretch to it. I opened the 3x and managed to get them on, but they were so tight they looked like I painted them on....and not in a good way. "Breathing optional" kinda tight. I had never been so relieved to take something off in my life! So sadly, they both went back. If they had just 1 size bigger...a 4x might have been perfect to fit my 2x, rectangle shaped body! Perhaps if you are in between sizes on the lower end, or have an hourglass/flatter stomach type of shape, just 1 size up might work. Unfortunately, I needed 2 sizes up for comfort and they don't make them up to a 4x on the website:( I had the same issue for the black ones although I found that the black ones fit just a little bit bigger....but not enough to make any significant difference though. Long story short, size up to be comfortable! To me they look and feel like true denim and if you can get the right size, they are quite flattering as well!
