Opinions from experts. On the advice of some lovely person here I ordered my mum some Bravissimo bras to try- she is 80s and lives some way from her nearest shop.
She measures 32.5 under her bust and 37 over- but because of her age, I think the cup size is an underestimate IYSWIM, because her boobs are quite soft and low slung, and when measured over a bra they are flatter - does that make sense?
She normally wears a 36D or 34DD, so I sent for 32F 32FF 34E and 34F.
She says they are all too tight and show her back fat. She is going to try to get to the store to be fitted.
However, TBH her current 36D ( it's a Fantasie) does not provide her with much support AND she was using an extender too at the back! She's just over a size 12 dress size, weighs about 8.5 stone ( her hips and waist are smaller than her bust) and there is no way IMO she is a 36+ back. She's always been told she has a tiny back and big cups.
So- what's the opinions on back fat? I dread she will end up with droopy boobs due to a bra that's too loose again.
