Yeah, I don't really like that it's kind of a taboo, but it is and that does pose a bit of a problem at work. I just wear a small extra shirt underneath my regular one and things become less noticable. Winters are fine, as I always wear more than just a shirt :D
Oh wow, I never really thought about hugging as I'm not much of a hugger myself. I guess I wouldn't make much of a problem of it, but apparently, others do! Not really sure how to fix that little issue, except for not caring about what others think. Better yet, simply don't hug the ones who talk bad about people without bras on!
