Yeah this guy and huambrillo have already nailed the answer but, despite what the media/beauty industry would have you believe, there are different breast types (and nippple types) just like there are different types of noses.
I have a personal preference for close set (narrow root) tear drop shaped breasts but will take almost any type as long as they are big enough. I also rep wide rooted breasts that continue under the woman's arms because they have the potential to hold the most volume and they look "hulked out", less sleek - see rodion busty candid.
