DD1 desperately needs a new bra - boob or bust say she should be in 28C or D (she only measures 26 underneath, but presumably this is not an option), but I ordered this John Lewis bra in 28C, but she had a bit of double-boob, which didn't seem appropriate for a new bra, and it does not exist in 28D, in fact 28D seems to be a bit of a black hole as there is not one 28D bra on the John Lewis website and the only one on the Marks and Spencer website (and a sports bra to boot!) was clearly not actually a D cup when it arrived.
Where else can I look? What can I do? I have ordered 30C in the mean time, but I don't know how good the band will be. Where does your slim daughter buy her bras?!?
