I found a video of this woman on YouTube. I really like her - she's ridiculously pretty, and she has a really beautiful figure and shape.
The video is here:
https://www.youtube.com/watch?v=bCvNTobgEGkIn it, she discusses various bras (and tries them on), her fitting/measuring, bra sizes and her shape etc. She gets most of it right about bras/sizes etc (although, her interpretation of the size of the band going around the body isn't exactly a measurement of the circumference of your torso - it can be smaller, or larger, depending on the cup size of the actual bra).
She states that her size is 30JJ and her sister size is 32J (I'm assuming these are UK sizes, because many of the bras she's discussing are UK bras) and she prefers to wear a 32J because it's more comfortable. This seems about right to me - in the video, when she's trying on the various bras, the 32J seems to be the one that fits her best - flat against her breastplate, no spillage (although, depending on which bra, there's sometimes a little overspill at the top - and there's one bra in particular which isn't even a bra at all, it's more like a bag for carrying onions). I guess, depending on the brand of bra - and how comfortable she feels, then her size will vary slightly (mine does). The Panache Cleo looks like a reasonably good fit on her, with slight spillage at the top. But she has such good shape. I wonder what height she is?
Also, I *love* that she knows about which set of hooks to start wearing a bra on. (Top tip: you start on the most loose setting of the hooks and work your way in as the bra ages and stretches - that way, it lasts longer).
