If you read my piece on Breast Implant Sizing, you can see that the volume is only half the story.  When considering a breast augmentation, we need to look at the width of the chest as well.  Wider chests require more volume to achieve similar looks to a narrower chest.  

Here is another example–this is 700 cc at 4 months.  This is a silicone breast implant, although I think saline breast implants look the same.  (see Silicone Breast Implants for more about implants).

You can see how the implants have fallen into place a little more compared with the example in the last post.  And again, I have no desire to make anyone larger than they wish–but if someone is going to go through breast enhancement, I certainly hope to get them to the size they want.
