As the title states I recently measured myself because I wanted to buy a new bralet and apparently I’m either a 34A or a 36A?? Which like, what? My whole life I’ve been wearing 34C and i actually find that the cups are a little small and I do have some spillage which is the only reason i decided to remeasure myself and now I’m so confused! How can I be a 36 band size when I’m measuring at 31.5?? I thought the number in a bra size indicated the band size, so like?😭Please help!
