Hmmm. I went from a 32DD to a 30E. Many companies say that bras are on a sliding scale e.g. increase band size and decrease cup size equally equates to the same fit but that is total crap. Anyway, I dearly wish (please god if you are listening!) that the next step in my primal journey, coming off the hormonal contraceptive pill, does NOT cause boob shrinkage. 30E sounds impressive but it isn't really, I have a little ribcage and a nice handful and I WANT IT TO STAY THAT WAY!
