Yeah, the one on your left: <--
Hrmm, there's something hideously wrong with it.
Something about your left breast is different from your right breast, and not in a good way. You should be really ashamed of it.
Go back in front of the mirror and look very closely, don’t come back until you’ve found what the problem is. It could be something like an odd color, wrong shape or weird spots or bumps.
Whatever it is, I’m starting to wish I hadn’t asked you to take your bra off.
