Here's an article about being inappropriately braless, or shall I say noticeably braless at work.

So who would go braless often? And why...

Other matters could be a bra that doesn't have sufficient cup lining....

I'm only posting this because obviously some women are ..braless /show sufficient cleavage on the job otherwise this article wouldn't be written.

Oh! I say no cleavage at work! It can be distracting and in my opinion, in poor taste. Some have jobs that require them to wear a uniform that shows cleavage but that can't be helped.
These new baby doll dresses and empire waists which are trendy are making all sorts of cleavage appear! I think that it doesn't work during the day at a certain age but if you are big on top, is it EVER, at any age, a good, attractive idea? I don't think so. I've seen it age some women who are older and show their cleavage thinking it is their "stong point," so far as their bodies. The showing of cleavage in the case of older women can be aging.
Sometimes it's hard to hide! No one wants to go around wearing things up to their chin so some dresses and tops can be revealing if you lean over, for example. In the case of "accidental cleavage," I think, oh well! It can be okay in the case where you are covered but now and again when moving, your cleavage shows.
Bras can be attractive and really pretty ones on some bodies that cover well can be ok, in my opinion, if some of the bra shows. This works when a woman is thin, I think, or if heavier, make sure the bra fits! In good taste, I say!
But at work? If you don't have to, I say "Non!"

If I went braless at my full time job people would be running for the hills! Aside from being a teacher, I am also a staff developer for my district. One of my jobs is working with new teachers. We make a huge point with them that they should have work clothes and play clothes and never the two should meet at work. Because of the styles today, and the fact that so many of them are low cut, we always need to emphasize this. Actually, it makes me a bit crazy that we have to coach them about professional work attire, but we do. We tell them we don't want to know if you wear a thong and we don't want to see your tattoos. The female teachers face more of a challenge than the males.

I will admit that when I am working at home on my business sometimes I am braless, but the only one I can scare is my children or the mailman!

Oh gosh, while in military, I was braless! I mean, I wore BDUs w/ t-shirt and cover, thus not noticeable. To this day I prefer braless, yet not very attractive, thus nowdays I'm only braless while working in the yard - back to nature if you will.

Okay, I wear a bra at work, but I hate it. It is the last thing I put on and the first thing I take off when I enter my home. I am sitting here braless right now.
