I know what you mean about the hug and a bra irritating it. It drives me insane some days. Luckily, I am home alone most of the day and can lounge around without one.....but I
have to wear one if I go out. There's no getting around that!
I have found that a good support or posture bra helps. It does take some getting used to because it is a little constricting but after I get used to it I find it actually helps. I guess it forces me into sitting up straighter. I've found that I can breathe a little better....or at least get a good deep breath.....when I wear one.
Playtex has some really good ones. Here's a website that has some awesome deals and they're really reliable. I order from them quite a bit. Their online address is
www.juliasbrashop.com.
Good luck!
