Kat:  I have a small bust and frequently don’t wear a bra.  This is mostly OK except during cold weather when I have some embarrassing situations.  What causes this, and is there any way to keep it from happening or any way to tell without looking at oneself.  I don't mind if people know I'm not wearing a bra, but I get embarrassed when I "show" and they stare.  

MYNIPPON:  Well most of the time this happens if the temperature is a bit low.  Additionally, when you are dressed without a bra whatever fabric is in touch will rub more frequently (as opposed to a bra which does not stimulate all that much since it is rather tight) and cause the same stimulation that you will experience during touch.  Hence the result, without even your realizing it.  So there is really not much you can do about stopping it from happening.  And even if you realized what was going on, there is no way you can do anything immediately.   The simple and most desirable solution is to wear a bra, of course.  However, if you don't wear a bra, you can wear, for example, a chemise?  Or just wear a top that is made from a thick rather than a light fabric.

Mary:  Yes, I know that if the temperature is low this will happen automatically and I try to be careful.  This generally happens when you walk from outside to a store where they keep the air-conditioning really strong.  However, I have also heard that it can happen by looking at an attractive man in a public place, for example.  Is this the reason why men are so curious to look at us?  Do they think that they are the ones responsible for our response?

MYNIPPON:  It is true that women experience this due to visual stimulation but it is not so simple as just looking at a cute guy.  Therefore, another man or woman would be naive to think that  it is because of his or her presence!!! Another fact that we want to mention is that many women simply have them very large (or long, should we say) that either just cannot be hidden even by a padded bra or they jut out.   Depending on your size you have to determine what bra you can wear, what fabric it has to be, and what type of tops and blouses would work for you.  Well-knitted fabric is generally the best.  Light, high-quality cotton can be as sensitive as synthetic fabrics like nylon and silk or satin and should be avoided.  The see-through bras that are manufactured from the thinnest material are the worst because they are so flimsy.  The same applies for the tops too if they are made from a synthetic fabric. Hide your chest discreetly  - so put on a jacket or a scarf and then take it off when you wish.  (Related article:  Let your bra show)

Kay:  The reasons I stopped wearing a bra in the first place was that most of the time it looked as if I was not wearing one anyway, since my bust is so small.  I know that a lot of women can get away with this.  I usually wear somewhat tighter tops and light fabric bras to keep mine in place but that made the problem worse.  How can you really tell beforehand if they are likely to show through a particular type of bra?  How many layers do you need?  I might add that highly padded bras actually look unnatural.
