DEAR MISS MANNERS: What is the most appropriate way to tell a female colleague that her thong is showing above the waistline of her pants when she is seated? I wouldn't hesitate to politely (and discreetly) tell a co-worker if her slip were showing, but this just seems different.
GENTLE READER: That is not the only thing that is different now. You can no longer count on ladies being upset when they find out that their underwear is showing. Miss Manners suggests saying quietly and neutrally, "You seem to have some elastic or something showing," so as to warn those who may care and not appear to be chastising those who do not.
