hi hun, i’m the same stats as you, just a bit shorter. I’d go for the 300, as you’ll probably measure a D but look a C cup in clothes. Fake boobies always measure bigger than real ones! X
hia faye im very similsr to u i am 5 ft 3 just under 8 stone and i am a 34 a the dr advised me 260 300 nat most he said they might look a but fake but im takin the chance and goin with the 300s however debroah has told me that if the dr thinks they look odd or wierd on the day he will put 260s back in lol
