I am ALWAYS a size 5, ordered these in a 5 and they were an entire size too big. Will be returning these tomorrow, but so sad they don't have a size that fits me! Would recommend ordering a full size down if not a half size. Other than the size not fitting, these are super cute. The fabric is not as thin as i expected which was nice and the elastic on the back strap would have been a nice detail if they had fit.
