Uneven breast after 6 months

I had a ba and I had noticed an uneveness since the begining but just listened to my PA and waited. Well, its been 6 months and I am concerned because my left breast looks fuller than my right.

Two PA's including the one I chose to have my BA done with mentioned the fact that I have a clavicle that stand out more than the other. I don't know if this has something to do with the uneveness. My guess is yes, but I still feel that the fullness is different. Will a revision help?
