And this is likely made increasingly common due to the decline in the wearing of suits over the past few decades.
When many men (basically all men in "white collar" jobs, and plenty of men in non-white collar jobs) regularly wore suits, many women were good at judging a man's place in society by his suit. When most men don't routinely wear suits, that skill isn't really worth cultivating for many women.
These days, just wearing a suit - any suit - is often enough to impress.
I guess I agree with this, but I would add that it wasn't just women who were good at judging a man's place by his clothes, it was everyone. I don't think that's just a feeling, either. Judging by the number of men's fashion publications, the style of menswear ads, and the look and feel of vintage clothing, men really did seem to know and care more about what they wore decades ago. That's arguable, of course.
