I'm a size 28. I usually wear SFAM or Citizens. I also have one pair of True Religions. I love Rock and Republics. However, I've only tried on one pair, out of many, that fit. I bought them!! I was wondering if you have hips or a slightly large a** do they fit? They mostly seem to gap in the back and show a plumber's crack. Does anyone else have this problem? Suggestions, comments please.
