I have them and love them! I'm about 5'7-5'8 and petite too (usually a 0/2). I had to size up (I am a 26 in most jeans, and a 27 in these, but I don't like jeans to fit too tightly), and they're pretty low-rise (maybe 6.5-7"?). They are also very long -- the inseam is close to 35". They fit me very much like this picture of the Bobbys: http://goclothing.com/womens-truereligion-bobby-darkbul.html
