Iaboy I am not sure those sizes are any alike I think she would be far closer to my size using xxls which was 32c to now and more 30gg(and still going) I am female so the positioning would be more the same too and if you have emtipness or sagging you want to increase the base size not crush it that would do the opposite I think for you it works because your start of breast tissue is still narrow so it focuses on that tissue more to have narrow for a woman who has big breast the breast tissue covers much more chest and wider will help round them and add fullness do you see? Starting breast growth is different to reinflating already big breasts because the size she adds will be in fullness more than outwards this is why a cup with space for this is more important.
As I said Lucy can be extremely frustrating when you have to argue to get the right size as women we know our breasts better than a strange sales woman.
