Answer

bust size or bust measurement is equal to bra size - 36C, or whatever system of bra sizes is relevant in your country.  You can ask 'what is your bust size/measurement",  not what is your bust.  
Bust doesn't mean 'breast' it refers to both breasts.  So a woman has two breasts, but one bust.
