Sorry I know this is a done-to-death topic!
Currently in a 32B but have lost weight recently and it's started to ride up from under the boobs so I think the band is too big, and I am not filling the cups.
Am I right to think with those measurements (done in I think the correct way, i.e. 1. tight under bust and 2. Leaning forwards 90 deg and measure round lowest hanging point of boobs) I should be looking at around a 30DD size?
