Does what I want exist? I've been searching online but can't find what I need, hoped someone here might have the answer...
I've always had small breasts, a B cup with generally soft nipples pre-children, which post-children have frustratingly morphed into a AA cup with permanently erect nipples. If I lift my arms above my head then my chest is literally flat as a board apart from these blooming nipples. I don't really mind the flatness of breast and at home will cut about without a bra quite happily, but I wouldn't be comfortable doing that a work. At the moment I'm alternating between a padded bra which puts me back to a B cup, and a C cup bra which I got just before stopping breastfeeding, which is not padded but holds its shape under clothes....but what I really want is something like a grown-up bralette, lined enough that it hides my nipples but not padded to made things bigger, doesn't really need to offer any support at all, maybe in a slightly lacy design with a proper bra strap at the back to help me not feel like a pre-teen 
Anyone know of anything like this?
