Everyone's has one breast bigger than the other! Don't worry. My right is bigger. Don't panic - they even out more as you age but they will never be both the EXACT same size. It isn't noticable, however.
Having one breast larger than the other, in most cases, is normal. No one is perfectly symmetrical from one side to the other. If you look closely in a mirror, you may also notice that one ear and one eye is slightly lower than the other, and one nostril is slightly larger than the other. The same goes for hands and feet. If the difference in breast sizes is really a problem for you, the only way to get them perfectly matched is through surgery. By the way, not many people other than yourself, are going to notice, or think it's unattractive.
