jabber, the problem is that bra sizes aren't consistent. Different styles and different manufacturers have sizes that may be off from what your size actually is. I have to try on a bra then sit, stand, bend, stretch, etc. to make sure it's going to stay in place and be comfortable. Even then, there's no guarantee that it will feel as comfortable at the end of the day as it does when you first put it on. As I said before, I hate wearing bras!
