Hi sue,
I asked for a full D and was offered 260 300 and 340, i have opted for biggest from reading what people have said on here and i think if they were going to look ridiculous he would have offered ?????? hopefully ha ha! what size are you looking to be? my friend was a 32A and had 380’s shes now a DD or E in some shops and was measured a FF in la senza so I think it depends on the person, its all very confusing!
Good luck tho not long now
xx
