Let's have some examples eh?
Julia Roberts is a 34B - they tried to maximise her assets in the movie Erin Brockovich (from which this still was taken) to make her look as large as possible.
Jade James (UK model) is a 34B/C.
Kelly Brook is a 32E and a lingerie model at that.
Sarah Michelle Gellar apparently wears a 36C (I forget where I read that - if I were guessing I would go for a B-cup).
I am a 34E. Just trust me okay? Or else,
you prove that I would fit better in a 36B than a 34E.
