I used to be a 38DD before I had children, but having gained two children and lost three stone, my boobs aren't what they used to be.
I'm now a 32F (measured at Bravissimo) but my boobs are like poached eggs in socks and perch nicely on my ribs.
I've got a ball coming up in September, and would love to wear something like this but wouldn't have a clue what to do with my boob support!
