Good morning, I see you've been busy 
For the ladies that have said that they are more fleshy at the side than the front, and struggle to fill a smaller cup but measure bigger.
The cup needs to extend as far as your breast tissue does. This can vary massively, and cannot be fixed by scooping, unlike migrated tissue.
The narrowest styles are more projected forward (e.g. Cleo by Panache etc). You need the opposite.
My best findings so far for you are the Fantasie Salsa, the Fantasie Belle full cup, and the new Tutti Rouge range which was launched at Bravissimo recently. The Belle comes up a cup bigger than the Salsa.
You need to avoid any wired style that has a side sling as that will dig into the breast in an attempt to push it forward.
For a soft cup option, the Royce Charlotte is pretty good, if a little functional, and their Sadie is a bit softer and prettier.
I'd be lying if I said these were vavavoom bras, but comfort has to have some say and the Salsa is quite delicate, all things considered.
