Well, I'm going to give a detailed review because there's not too many out there that answered all the questions when I bought these pants. I'm 5'5 and range between 125-130 lbs. longer torso than legs. Regular build. I followed the reviews with these and got a size 4 in the gravel color. They were a little weird fitting at first, considering I have short legs and these DO run long. Which is good for those with long legs but us with moderate/short legs you'll need to cuff them, or just wear them regularly because they really don't look that bad. After the first day I wore these, they definitely stretched out and at first I was concerned because it definitely made them feel too big. But, they have shrunk a wee bit after washing and drying them a few times, making them more form fitting. But they're mainly made with organic cotton so it's expected. Just be careful if you're not one of those people who are between sizes, like me (2-4)
I honestly love these pants so much that I've taken the time to look into Prana Pants/Jeans and have ordered several other pairs. For the longest time I wore Size 2 regular/longs in American Eagle Jeans, so for those of you who wear that size in those jeans and are the bigger side of the size 2, go for the 4. If you're on the smaller side, go for a size 2 in these. Because you know Americans Eagle, all about thAt stretch!! As with these, they stretch out but not a whole lot. I definitely recommend wearing these pants for a day or two to see how they fit overall, because they do shrink like the tinyest bit, and you may or may not want that. Great pant, worth the money!!!
