Many patterns are from 6-12 or 8-14 for the smaller size. But the 14 tops at around a 36 inch bust I believe. Then the next size up is usually a 14-20 or 12-18. And even though they get pretty big, they aren't the same as American vanity sizing. I'm not sure that vogue does a whole lot of the larger patterns. But fatties often like to adjust the patterns tentlike in order to "fit" the pattern.
