IMHO, women dress for other women. They are trying to impress their friends/teachers/shadchanim/future MIL & family. Shouldn’t rebbetzins/morahs(/mothers) be setting the example?
The only men who should be paying attention anyhow are those on a date, and (dare I say?) as long as she’s not a complete slob, he should be paying more attention to her middos anyhow.
By the time a father has sons in shidduchim, he/the boy’s rabbeim (I’m sure have been)/should have been modeling good middos for years, or at least much sooner than two weeks before he comes out of the freezer. I could be in the minority, but I think it’s less important for my son to know how to schect a cow (unless he wants to be a shochet) than for him to know how not to eat like one.
