Prana knickers are the best!
I have these along with the Audrey and Mara style knickers by Prana. These fit slightly tighter in the thighs. But, I love all of them just the same. These are form fitting but not unflattering in the crotch. I have noticed lots of tight fitting capris tend to give off that "camel-toe" appearance, which I prefer avoiding and these do not. I usually wear a U.S. women's 2 or 26 in pants. With Prana I find that XS fits me best. I am 5'4 115-117lbs for reference.
