I hope this review helps others find the right size. This is my 3rd purchase of these pants to get the size right. When they fit, they're incredible, but wait until they are on sale which is what I did. I'm 5'5" and weigh 180 and my normal size is an XL or 1X depending on the brand. But in these pan...ts, a Medium fits me perfectly. I first bought an XL which was ridiculously huge and too long. I then bought a Large Petite which was still too big but now too short. I finally purchased a size Medium Regular Length and they fit incredibly. To address other reviews: these pants don't really look like jeans on me but very well made sweatpants. Second, they are true French terry and the weight is moderate. Third, they are not "baggy" as the title suggests but have a very wide leg. The sizing is very off. The waistband of these pants is very big and expands a lot. My waist is just over 40 inches and the medium size I just received measures only 30 inches but they fit great - which probably seems off but they do. Not only do they fit around the waist, they do not bind at all and are very comfortable. And the hips and rear fit well (42 inches on the medium), with the length just touching the floor (29 inch inseam on the medium).It seems that with these particular pants, the larger the size the bigger the waistband, the wider the leg, and the longer the inseam. I don't understand why an XL would be so much longer and wider in the legs. I suggest sizing down about 2 sizes, and know that the larger sizes have very expansive waists with no drawstring to keep them up (there are belt loops however), much wider legs, and a much longer inseam. Also, they are color washed, meaning that the color is lighter than the photos.The navy has a faded look to it and so does the black. They are incredibly comfortable, well made, and extremely good looking when you find the right size and length. Good luck!
