I know that some women have been showing cleavage for a long time. (And some people have been criticizing them for it for a long time.) But in my experience, it’s been getting more common in the last five years or so, and it’s showing up in work environments where you wouldn’t expect it.
I recently meet a woman who is an insurance agent–traditionally considered a white-collar, “professional” job. She was wearing something that showed a little cleavage. But what inspired this thread was something I, at least, have never seen before – her picture that is on her business card shows her in a very low-cut top that shows a LOT of cleavage.
I also met a real estate agent who was wearing a tank top that not only showed cleavage, but also showed a significant portion of her bra.
I know that there are some people who would be less likely to patronize those business people based on that. What I don’t know is how wide-spread such an attitude is.
