I haven't read Mademoiselle for years, either, and I'm way past 30.
Mode magazine, which is targeted toward women who are a size 12 or larger, as I am, is also going out of business -- the last edition is this month's (October).
That's a shame. Unfortunately, many people just don't realize that 60 percent of American women are a size 12 or larger, including women who have purchasing power.
Mode's ceasing publication will mean fewer advertising and editorial article/photograph outlets for stores and clothing makers wishing to reach larger women.
I honestly doubt Vogue (which I do read) would pick up on that.
