hi Jackie, I am 5’7″ and use to be a small b cup and i had 380 overs and now in a 34e or 36dd in La Senza. Although a DD / E seemed huge to me before my ba, you just get use to the size so quickly, and when dressed i don’t think i look that big at all. I had my ba last August at the age of 39, after wanting one for over 10 years. I am so happy to have boobs at last, and being quite tall, they look right on me. So many girls say to go for the biggest size offered, as it is a lot of money to pay, and you don’t want to be disappointed afterwards, wishing you had gone for the bigger one. There is hardly any differance between 340 and 380 so i’m sure that either will look fab on you.
Good luck, Jacqui xx
