just to say, that the measurement under your bust is accurate.
mmj, the cup size you wuold get form one of those formulas gave you
46dd, i bet the cup fitted ok?
46dd is equal to
44e
42f
40g
38h
36g
so the bra size you are wearing is almost spot on, and was dependent on the style and your overall shape.
Yes women would go ruond in a 44e becuase their boobs fitted in the cup, but the back/band (on you) would be up round your neck!! The problem lies with the basic fact that most bra's or companies don't make bras' in enough range of lower rib sizes.
Even those with smaller rib/back sizes get the same problem.
I was wearing a 36 c when i started at Rigby,as basically m+s didnt do any other size like a 34d (yrs back) so i had to get bra that my boob fitted into.
as it tunred out i was 32dd.
36 c
34 d
32 dd all have the same, cup size. if you held one over the other the cups would be the same size, only the band is getting larger. that's how sizing works.
