it depends on the person, one of my friend is a size 12-14 and she looks good because she has a shapely figure whereas my other friend is the same size, but as she lacks curves, and has a hanging belly, I think a smaller size would suite her more. Size 8 and bellow is skinny for an average women of medium height,bone and muscle mass. 10-12 is slim depending on the person. 14 or upwards is comfortable.
