If McCalls/Butterick were more explicit about what they were trying to do they would be much more effective in bringing their pattern buying customers along with them rather than p*ss*ng them off with what looks like a deliberately sneaky move. I've read the discussion on pattern review now and there are certainly some clever pattern sleuths there. And I've realised I have one of those patterns when it was McCalls.
It does make some sense to focus ranges on different demographics but I would have thought that alongside younger women who perhaps don't have kids (yet) although likely to be working, quite a few of their customers are older with more time to sew and sometimes more disposable income so they can surely keep us all happy!
