Aaahh! That pic takes me back to when I was a big breast novice!
I was always interested in breast, especially when you could see the outline of the bra beneath there shirt. One day I came to the realization that if you could see the seam in the middle of the cup because it required two panels, it must be a very bra! I'm sure makes and models of bras differ, but the biggest I've seen is a 36DD and there still wasn't the magical seam in the middle.
